At the military parade on September 3, 2025, marking the 80th anniversary of the victory in the War of Resistance, the 4th generation domestically produced highly mobile radar of the air defense and missile defense early warning detection formation made its debut. It can accurately detect stealth aircraft and ballistic missiles, safeguarding the safety of the skies. In the civilian field, although drones bring convenience in various areas, their disorderly and malicious use has caused issues such as privacy invasion and intrusion into sensitive areas. Against this backdrop, anti-drone technology has emerged as a key force in defending low-altitude security.
Radar detection
In the three-dimensional anti-drone defense system, detection is the first line of defense , and radar detection undoubtedly holds the position of a "high-level sentinel." Radar detection is not only an unsurpassable technical benchmark but also the core choice for high-level defense scenarios. Thanks to its relatively stable performance, radar can withstand the impact of complex weather and is a key link throughout low-altitude security protection. Taking Wuhan Leikeda Technology Co., Ltd. low-altitude security series radar as an example.
Band issues: Advantages and disadvantages of X-band/S-band/C-band
X-band:
Advantages: High resolution, strong clutter resistance
Limitations: Detection range (3-8 km), greatly affected by adverse weather, susceptible to electromagnetic interference
Applicable scenarios: Airport clear zones, medium and large event protection
S-band:
Advantages: Long detection range (10-20 km), strong weather resistance, stable anti-interference
Limitations: Low resolution, more low-altitude clutter
Applicable scenarios: Border areas, base perimeters, nuclear power plants, and other all-weather large area protection
C-band:
Advantages: Balanced performance (6-12 km), medium weather adaptability, higher accuracy than S-band
Limitations: Low-altitude clutter requires algorithm filtering
Applicable scenarios: Industrial parks, logistics parks, and other medium-sized areas
Electro-optical identification and tracking
In the anti-drone detection system, the electro-optical system is the radar's core assistant—it uses a high-precision electric turntable to receive the radar's rough target azimuth and distance information, then aligns the field of view to the target airspace at millisecond speed for rapid connection.
Wuhan Leikeda Radar-Optical Integrated Machine With the narrow field of view 、 and high-resolution imaging features, it can be paired with different radars to achieve various detection effects. During the day, a camera is used to present drone shape details. 、 At night, a an infrared thermal imager captures thermal radiation, accurately distinguishing whether the target is a drone, bird, clutter, or specific model.
Facing target maneuvering or electromagnetic interference, relying on high-angle tracking accuracy and image tracking algorithms, it continuously and stably locks onto the target and records the process for review, forming a "wide-area search and fine discrimination" + mode with radar, jointly strengthening the anti-drone detection defense line. ” 模式，共同筑牢反无人机探测防线。
Applicable scenarios: Key areas such as border defense, maritime defense, and bases.
Countermeasure fields
" Anti-drone " soft countermeasures:
Civilian anti-drone soft countermeasures with the non-destructive and low-risk characteristics of "no damage, low risk," have become the core choice for civilian low-altitude security protection. 核心选择。
Soft anti-drone countermeasures mainly achieve navigation deception 、 interference suppression 、 and navigation signal interference to force "black-flying" drones to land, be driven away, or return, and can select directional devices or omnidirectional devices as needed. Its core value lies in safety and controllability, avoiding damage to drones to reduce disputes and costs, while also preventing the risk of falling debris, resolving drone threats in civilian scenarios in a "gentle and efficient" manner. 。
其核心价值在于安全可控，既不损无人机减少纠纷与成本，又能规避残骸坠落风险，以 “温和高效” 化解民用场景无人机威胁。
Applicable scenarios: Key areas such as border defense, large conferences, no-fly defense zones, farming areas, and bases.
" Anti-drone ” Hard countermeasures:
Hard-hitting counter-drone measures to " Physics destroys / Deals a heavy blow "At the core, there are four main categories:
High-Energy Laser Weapons: Requires recharging; delivers precise "line-of-sight strikes" capable of burning through drone components. Ideal for mid-to-close-range precision destruction, offering rapid response—but performance can be affected by weather conditions.
High-Energy Microwave Weapon: "Surface Strike"—delivers powerful microwave energy to blanket an area, disabling the electronic components of drones. It can simultaneously engage multiple targets, making it ideal for intercepting swarms of unmanned aerial vehicles.
Artillery-Air Defense Coordination System: Combining artillery shells with anti-aircraft guns, the shells can destroy long-range targets, while the anti-aircraft guns engage medium- and close-range threats—making this setup ideal for providing extensive protection over a wide area of critical locations.
Kinetic Kill Vehicle: Launching small interceptor missiles to directly collide with drones, this system boasts high precision, making it ideal for targeting high-value or high-speed UAVs. Some models can even be integrated into vehicle- or ship-mounted platforms.
These methods are widely applied in Military or High-level protection scenarios , characterized by Completely destroy , but is prone to Wreckage , needs to be considered Drop-point safety 。
In an era when drone safety concerns are becoming increasingly severe, anti-drone radar—essential equipment for safeguarding low-altitude airspace—is playing an irreplaceable and critical role. With continuous advancements and innovations in technology, anti-drone radar will further expand its applications across military, civilian, and other sectors, ensuring the safety and stability of people's lives and society. In this ongoing "battle of offense and defense" against drones, anti-drone radar is steadily forging new, robust defensive barriers.
