The "Intelligent Low Altitude Security Automatic Defense System" of Huawei Vision has been successfully selected.
智能低空安全自动防御系统
1、 System Introduction:
The intelligent low altitude security automatic defense system integrates differential positioning system, radar detection system, passive spectrum detection system, precision optoelectronic detection system, wireless voltage based interference and deception system on the basis of deeply optimized self-developed control platform. It comprehensively applies angle compensation positioning, multi spectrum detection, heterogeneous system interconnection, multi-source data fusion, intelligent analysis and decision-making technologies, and uses multiple means of detection and strong hand processing to achieve rapid north calibration of the entire system after the vehicle stops. It provides guarantee for early detection, fast locking, stable tracking, and accurate identification of low altitude unmanned aerial vehicles. Multiple detection methods complement each other, and multiple frequency band interference interception can effectively guarantee low altitude security all day, all time, and all dimensions.
The system is mainly equipped for users such as public security, armed police, military, government, universities, etc. It is commonly used for the prevention and control of unmanned aerial vehicle targets in key areas, large gatherings, public places, and military locations.

2、 System advantages：
(1) Target classification recognition
The device supports single target and multi-target detection, and supports classification detection of human, vehicle, drone, and bird targets. With the help of high-performance and high computing power processors in optoelectronic devices, real-time and accurate detection of airborne targets can be achieved. Thanks to our self-developed recognition algorithm, similar airborne targets such as drones and birds can be classified and detected, improving accuracy and reducing interference from airborne targets. It can also be recognized in complex backgrounds such as cities and forests, reducing the impact of the environment on optoelectronic recognition; Two channels can also be simultaneously activated for detection, assisting in target tracking to achieve discovery and locking. The actual test results of birds and drones are shown in the figure.
(2) Target tracking
After completing motion target detection, it is necessary to perform motion target tracking. The tracking of moving targets in video surveillance systems is achieved by analyzing the image sequence obtained by the camera, calculating the two-dimensional position coordinates of the target on each frame of the image, and associating the same moving target in different frames of the image sequence based on different feature values to obtain the complete motion trajectory of each moving target.
For some more complex scenarios, traditional tracking algorithms are no longer applicable. By combining deep learning object detection with traditional tracking algorithms and optimizing tracking logic processing, the target can still be tracked in complex backgrounds, ensuring tracking continuity and adapting to different backgrounds.
The Hope-wish Smart Low Altitude Security Automatic Defense System supports multiple methods such as radar, spectrum, and recognition algorithms to detect targets. It can detect and automatically track targets in low altitude aircraft/airborne objects/areas, providing strong security and stability in the low altitude field and contributing to maintaining social order and public safety.
