The multi-dimensional and multi band collaborative low slow small target monitoring, early warning and damage system can be flexibly installed on mobile platforms such as unmanned vehicles, pickup trucks, armored vehicles, or fixed monitoring points such as outposts and border stations, for early warning, interference and strike of incoming drone swarms, solving the protection problems of border control points, important airport facilities, etc.
The system consists of a monitoring section, a tracking and identification section, a destruction and strike section, and a control center platform; The monitoring part is composed of radar and is responsible for tasks such as target detection and target trajectory generation; The photoelectric turntable is composed of visible light, long wave infrared, turntable, etc. Mainly responsible for capturing, locking, tracking, and identifying targets; Destroy dangerous targets outside the controlled area; The control center platform includes functional modules such as system management, electronic optical turntable, radar, unmanned aerial vehicle data, interception equipment, and management area situation.

III.I Monitoring (radar+photoelectric monitoring)
III.II Detection (algorithm detection, small target, infrared target detection, determining what the target is)
III.III Discovery (finding targets in the field of view)
III.IV Capture (Select box and target)
III.V Lock (Select box to lock target)
III.VI Tracking (the target always runs in the selected box)
III.VII Alarm Warning (Target Locking Alarm by Monitoring Center)
III.VIII Laser Lighting (When the target distance is 1200 meters, turn on the laser lighting to enhance the brightness of the target and make the video graphics clear)
III.IX Laser Drive Away (When the target is 1000 meters away, a strobe laser is emitted to drive away the target.)
III.X. Laser Blinding (When the target is at a distance of 800 meters, laser is used to irradiate the target's camera or other image acquisition equipment, causing the device to become blind and unable to capture video images)
III.XI Laser Damage (When the target approaches 200 meters, manually operate and activate a strong laser to damage the target.)
III.XII. Storage and playback
It can monitor and warn of damage to various aircraft targets such as drones, low-speed small aircraft, cruise missiles, light aircraft, aerospace models, light and ultra light aircraft (including light and ultra light helicopters)/gliders, powered delta wings, hot air balloons, airships, powered gliders, drones, unmanned free balloons, tethered balloons, large kites, etc. (24 hours a day) (it can also be applied to activities such as deicing, high-altitude removal of foreign objects, bird repelling, tree cutting, etc.)
Low altitude unmanned aerial vehicles pose a significant threat to the base management. Unmanned low altitude aerial vehicles are becoming increasingly mature, but the defense equipment for low altitude flight of unmanned aerial vehicles is not mature. Therefore, how to crack the drone attack, especially the drone "swarm" detection and strike under strong adversarial conditions in war, has become an urgent need for the base.
