Introduction:


The "Guardian I" anti-UAV defense system is composed of a radar detection subsystem, an optoelectronic tracking subsystem, a radio interference countermeasure subsystem and other equipment, as well as the RGS1000 low-altitude early warning and control platform. The system uses the radar detection sub-system to complete the detection, positioning and tracking of the low-slow and small UAV targets, guides the photoelectric tracking sub-system to perform video forensics, and guides the radio interference counter-system to deal with the target. 


Comprehensive use of multi-spectrum detection, heterogeneous system interconnection, multi-source data fusion, intelligent analysis and decision-making and other technologies to achieve early detection, fast locking, stable tracking, accurate identification and strong countermeasures of low-altitude UAVs, and multiple detection methods complement each other , a variety of frequency band interference interception, which can effectively protect the low-altitude safety of key places all day, all time, and all dimensions.

Product Appearance Drawing of Radar Detection Subsystem (Reference)


The radar detection subsystem detects low, slow and small UAVs by transmitting radio waves and detecting echoes. The radar echo signals of targets in the airspace are collected by the antenna feeder system, filtered, amplified, and down-frequency processed by the radio frequency components and transmitted to the signal. processing board. The signal processing board performs signal accumulation, clutter elimination, etc., and reports the processed radar detection target angle, speed, distance and other information to the data processor and system terminal.

Photoelectric tracking subsystem product appearance diagram (reference)


The optoelectronic tracking subsystem uses visible light cameras and infrared thermal imagers to automatically track and lock low-slow and small UAV targets, and analyzes the morphological features or motion features of the targets through image acquisition and processing to achieve target detection, automatic identification, locking and tracking, and video recording. Review and boot countermeasure devices. Provide command and decision makers with intuitive real-time image information of the target. Under the guidance of the distance, azimuth, and altitude information provided by the command and control system, the drone can be found, tracked, and automatically identified. Optoelectronic equipment can also conduct autonomous search and detection of short-range low-altitude flying objects, and implement auxiliary low-altitude surveillance.

Product appearance diagram of radio interference countermeasure subsystem (reference)


The radio interference countermeasure subsystem uses radio frequency technology to interfere with the flight control channel, GNSS signal and image transmission signal of low-slow and small UAVs. UAVs entering the coverage area cannot obtain satellite positioning information. At the same time, UAVs Both the control signal and the image transmission signal to the ground controller were cut off, forcing the drone to return or land and lose the image transmission function.
