Guard III Anti-UAV System

introduction:

The "Guard III" anti-UAV defense system consists of a radio detection and positioning subsystem, a radio direction finding detection subsystem, a radar detection subsystem, an optoelectronic tracking subsystem, a navigation inducement subsystem, a radio interference countermeasure subsystem and a portable ( Hand-held) radio interference countermeasure subsystem and other equipment and RGS1000 low-altitude early warning and control platform are jointly composed. The system consists of radio detection and positioning sub-system, radio direction-finding detection sub-system and radar detection sub-system to detect, identify, locate and track low, slow and small UAV targets, guide the photoelectric tracking sub-system to perform video forensics, and guide the navigation and inducement sub-system. The target is handled by the system or the radio interference countermeasure subsystem. 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.

The system is mainly equipped for public security, armed police, government and other users, and is often used for the prevention and control of drone targets such as prisons/detention centers, large gatherings, and public places.

Product Appearance Drawing of Radio Detection Subsystem (Reference)

The radio detection subsystem is a passive detection method, and the system itself does not emit any radio waves. The system can passively receive the image transmission signal and remote control signal of the target UAV, search, collect, find direction and intersect and locate the signal. There are low-slow and small drones invading the defense area.

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.

Navigation and inducement subsystem product appearance diagram (reference)

The navigation inducement subsystem simulates the real satellite navigation signal with high precision, controls the positioning output of the low-slow and small UAV navigation system, and sends false geographical coordinates to the UAV, so that it cannot use the navigation system to determine its own position and deviate from the predetermined route. Induce the flight control system to generate wrong flight control instructions, and then control the UAV to control the flight track, make it fall or control the UAV target to the space position set by the user for strike.

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.

RGS1000 low-altitude early warning and control platform (reference)

The RGS1000 low-altitude early warning and control platform can be connected to the radio detection sub-system, radar detection sub-system, photoelectric tracking sub-system, radio countermeasure equipment and other UAV detection, identification and countermeasure equipment at the same time. A comprehensive visual anti-UAV command and management platform that integrates the functions of situation display and control, alarm linkage, decision-making and command, record and evidence collection, and event retrieval.

Features:

radio detection subsystem

1) Passive radar, no radiation, hidden work, long-term use will not cause any adverse effects on the human body;

2) It can monitor and track UAV and flight control signals at the same time, and the detection speed is fast, which is convenient for early warning and disposal;

3) 360° omnidirectional coverage, which can capture UAV image transmission and remote control flight control signals hidden between buildings and trees.

radar detection subsystem

1) The ability to monitor low-altitude, slow and small targets, flexible deployment, fully automatic, and all-weather work;

2) The three-coordinate primary radar has altimetry capability;

3) Support unattended operation, reduce the difficulty of work, and avoid the interference of electromagnetic radiation to operators.

Photoelectric tracking subsystem
