Low-cost "Flying Mini Motorbike" Drones Rampage? Leiqing Technology Delivers The Optimal Layered Defense Solution

Recently, low-cost suicide drones represented by the Shahed-136 ("Flying Mini Motorcycle") have emerged as a new threat to modern battlefields and critical infrastructure. Boasting unique designs and tactical applications, such drones frequently render traditional air defense systems ineffective, posing a daunting challenge for defense authorities across nations. In response, Leiqing Technology, a long-standing specialist in low-altitude security, has put forward an ultimate solution: a layered defense system centered on soft kill technology, featuring integrated detection, jamming and hard strike capabilities.

I. Identify the adversary first: What makes the "flying mini motorcycle" so hard to defend against?

The essential threat posed by the "mini motorcycle" lies in its combination of low altitude, slow speed, small size, low cost plus inertial navigation, plunging traditional air defense into a predicament of difficult detection, unaffordable interception costs, and ineffective blockade interception.

1. Stealth + low-altitude flight, difficult for radar detection

It features an extremely small RCS (only 0.1–0.5 m²), equivalent to that of a flying bird. Cruising slowly at low altitudes of 100–500 meters for extended periods and concealed by ground clutter, it easily causes missed alarms for conventional radars.

Traditional air defense radars can only detect such targets at a range of merely 3–8 km, leaving threats already dangerously close once identified.

2. Inertial navigation dominant with strong anti-jamming capability

It mainly relies on combined INS and satellite navigation guidance. Even if satellite signals are temporarily suppressed, it can still fly toward the target continuously via inertial navigation.

Equipped with Controlled Reception Pattern Antennas (CRPA), it dynamically adjusts the reception pattern to enhance satellite signal reception and suppress interference, requiring sustained multi-station coordinated jamming and spoofing of its navigation signals for effective countermeasures.

3. Ultra-low cost with saturation attacks as a regular tactic

The unit cost amounts to only tens of thousands of US dollars, far lower than that of air defense missiles. It excels at swarm attacks that overwhelm defense systems by sheer numerical advantage, rendering the traditional mode of intercepting drones with missiles extremely cost-ineffective.

II. The Core Breakthrough: A Coordinated Soft-Kill Strategy of Precision Spoofing & Multi-Station Synergistic Linkage

Given that the "Flying Mini Motorcycle" adopts combined guidance of inertial navigation and satellite navigation, the breakthrough approach becomes clear: conduct continuous satellite navigation signal spoofing via multi-station coordination to accumulate errors in its inertial navigation system, ultimately causing the drone to deviate off course and lose control.

1. Early Warning & Precise Interference Window Control

Adopt an on-demand activation mechanism. Based on the drone’s cruising speed of 150 km/h, a 3-minute navigation jamming window is defined: within this timeframe, the drone travels approximately 7.5 km, and inertial navigation errors will accumulate to a level that triggers severe course deviation.

Jamming is activated only when targets enter the defense perimeter at a distance of 7.5–10 km from core assets. This ensures sufficient time for course deflection while avoiding long-duration emission interference against the surrounding electromagnetic environment.

If the penetration is executed at its extreme speed of 185 km/h, the flight distance in 3 minutes reaches 9.25 km; accordingly, the early warning intercept distance shall be adjusted to 9–12 km to guarantee an adequate jamming window. Meanwhile, jamming signals induce premature false alarms in hostile systems, generating frequent fake alerts ahead of real threats. This occupies system processing resources, reduces target identification credibility, and achieves effective suppression against the drone’s anti-jamming performance.

2. Multi-Station Coordination: Breaking Through Anti-Jamming Nulling

The Controlled Reception Pattern Antenna (CRPA) equipped on the drone can actively identify and suppress interfering signals while amplifying valid navigation signals, realizing directional reception, intelligent filtering and interference cancellation.

It is normally configured with 4 array elements, forming 3 anti-jamming nulls — capable of suppressing interference sources from three distinct directions. In upgraded configurations with up to 16 array elements, the system can counter jamming threats originating from 16 different azimuths simultaneously.

Adopting a multi-station coordinated mode can disrupt its spatial filtering conditions and achieve nulling breakthrough through the following approaches:

1. Deploy distributed multi-point jamming, making it difficult for the system to form deep anti-jamming nulls in multiple directions simultaneously;

2. Apply fast frequency hopping and blinking jamming to prevent its nulls from aligning with interference sources in a timely manner;

3. Implement wide air-domain and multi-angle coverage jamming, forcing uniform gain across the entire airspace and disabling effective suppression;

4. Combine complex modulation and multi-dimensional jamming patterns to raise difficulties in coordinated identification and interference cancellation on the drone’s side.

Dominated by Soft Kill:

The Lowest‑Cost “Swarm Buster”The core advantages of electronic jamming and signal spoofing lie in ultra-low cost and unlimited reusable capability. A single system startup can counter saturation attacks by multiple “Flying Mini Motorcycle” drones, unlike intercept missiles that are consumed upon launch. It generates no fragment collateral damage, making it particularly suitable for safeguarding sensitive targets such as urban areas, power stations, and oil depots.

III. Complete Closed-Loop Defense: Three-Tier System of Early Detection, Timely Jamming and Terminal Interception

To achieve comprehensive defense against the "Flying Mini Motorcycle", soft-kill measures alone are insufficient. It is essential to build a layered defense framework featuring long-range early warning, timely soft-kill suppression, and terminal hard-kill interception.

Tier 1: Early Warning — Block threats at 10–20 km with low-altitude detection radars

Dedicated low-altitude detection radars are deployed, which are deeply optimized specifically for low, slow, small (LSS) targets:

Through multi-station coordination, the detection range can reach 10–20 km, enabling accurate identification and continuous tracking the moment the "Flying Mini Motorcycle" enters the defense perimeter. Long-range full-domain awareness is realized via radar to deliver early warning, reserving ample response time for subsequent soft-kill and hard-kill operations.

Tier 2: Core Suppression — Timely Soft Kill to Disorient the Threat

Activate the multi-station coordinated navigation jamming and spoofing system. After targets enter the early warning range, power on the system on demand to continuously suppress satellite navigation signals and cut off the position correction sources for the "Flying Mini Motorcycle" drones.

Coupled with the accumulation of inertial navigation errors, the drones gradually deviate from their preset flight paths within the 3-minute jamming window, eventually losing control and crashing or straying far outside the target area. Adopting a multi-station coordinated deployment rapidly breaks through the nulls generated by their anti-jamming antennas, ensuring effective jamming performance.

Tier 3: Terminal Supplementary Defense – Optically Guided Hard Kill to Eliminate Slip-through Targets

For a tiny number of "leaking targets" that break through the soft-kill defense line, electro-optical detection equipment guides close-in weapon systems or laser weapons to implement terminal interception.

Within the final 2 kilometers, physical damage strikes or laser attacks are adopted to precisely target the engine section of the "Flying Mini Motorcycle", ensuring it crashes at a distance of 1 kilometer. Featuring controllable costs and rapid response, this serves as the last line of defense to guarantee absolute safety for core key assets.

IV. Core Conclusions

When confronting low-cost suicide drones such as the "Flying Mini Motorcycle", the traditional approach of intercepting drones with missiles has become completely ineffective — it suffers from an extremely poor cost-effectiveness ratio and cannot withstand saturation attacks. The truly optimal solution lies in the integrated layered defense system of detection‑jamming‑hard kill developed by Leiqing Technology:

• Specialized low-altitude detection radars deliver early warning at a range of 10–20 km, with warning distances precisely calibrated according to target flight speeds.

• Centering on early false alarm induction plus multi‑station coordinated electronic jamming and signal spoofing, the system activates on demand to disable satellite navigation and accumulate inertial navigation errors, causing fundamental navigation failure while minimizing interference to the surrounding electromagnetic environment.

• Finally, terminal hard-kill means (close-in weapon systems, laser weapons, etc.) guided by electro-optical detection provide supplementary interception, forming a fully closed defense loop.

This model can not only withstand large-scale saturation assaults but also minimize overall defense costs, representing the long-term reliable response against threats posed by drones like the "Flying Mini Motorcycle".

Since ancient times, the emergence of asymmetric threats has often signaled a fundamental restructuring of defense logic. Nowadays, as low-altitude security increasingly becomes an essential cornerstone of national critical infrastructure, solutions offered by Leiqing Technology support early warning coverage at 10–20 kilometers along with wide-area spoofing through multi-station coordination. This represents not merely a closed-loop technological response targeting specific threats, but also a reliable, deterministic security foundation built for core critical facilities. Moving forward, we will continue advancing the evolution of low-altitude defense from passive emergency response toward a systematic, proactive protection barrier, so as to further fulfill our core mission of making low airspace safer for all.
