Overview of detection and countermeasure systems
 The counter system consists of detection radar, photoelectric & counter-integrated equipment, and integrated ground station monitoring equipment. The system has complete intelligent linkage, based on low-altitude detection radar, to realize detection, early warning and discrimination of drones.

At the same time, the system can obtain parameter information such as distance, azimuth and speed of the target and form a motion track on the map, and send the information to the control system. The optoelectronic & anti-integrated device can be used to track the target in order to achieve photoelectric monitoring and RF interference.

The system can be used at fixed points or mobile. A micro-aircraft target with a radar scattering area of RCS ≥ 0.01 m2 achieves a maximum 3 Km detection range, a spatial coverage of 360°, a pitch angle of 18°, and a maximum effective offset of 3 Km.

Introduction to the main components of the system

1. Detection radar
The detection radar adopts an advanced all-digital phase control system, which can separately detect and track multiple targets. At the same time, the number of tracking targets is greater than 100, and the speed, trajectory, distance and orientation of the target are displayed on the terminal map in real time. The system integrates a variety of anti-clutter algorithms with good clutter suppression. The device is small in size, light in weight, easy to erect, and has strong application scalability.

2. Photoelectric counter system 
2.1 Photoelectric counter system
The photoelectric counter system mainly includes a photoelectric part, a counter and a gimbal, wherein the photoelectric and counter parts are integrated design, installed on the gimbal. If the monitoring center confirms the target attribute and needs to counter it, you can make the following choices:

2.2 RF suppress interference
According to the orientation of the radar detection output, the system directs the directional counter to the target, so that the target is in the direction of the maximum radiation of the interference signal. Thereby, the communication, control and positioning system of the target drone is interfered, and the data link and radio communication between the target drone and the drone operator are quickly cut off, so that the target drone cannot fly normally, with forced landing or return back home.

2.3 Photoelectric confirmation tracking
There are two kinds of photoelectric parts: visible light and thermal imaging. The visible light part is 45x of the camera lens, and the back end is 265 encoding. The ground station can realize the video tracking function. Thermal imaging is currently selected by aircraft, which is a 19mm lens, and it is still necessary to select a more suitable lens in the later stage;

2.4.High-speed PTZ linkage
The counter and the optoelectronic part are erected on the same gimbal, and the gimbal is controlled by the ground station. The ground station controls the rotation of the gimbal according to the azimuth information of the radar, and follows the target in real time. During video tracking, the gimbal can be controlled to rotate vertically and horizontally to ensure that the target is followed in real time;

2.5Introduction to Target Tracking
There are two kinds of tracking methods in the system, one is radar tracking and the other is video tracking. Radar tracking is mainly used in the early detection of targets. In the case where the photoelectric has not yet found the target, the radar tracking can only track the target from the horizontal, that is, the azimuth tracking, because it cannot obtain the height information of the target. On the basis of radar tracking, video tracking can adjust the target of the gimbal, find the target, and adopt the video tracking method to accurately track the target, confirm and strike the target. The video tracking priority is higher than the radar tracking, that is, when two simultaneous selections are performed, the video tracking mode is performed;
