The invention discloses a low-altitude defense system based on artificial intelligence. The low-altitude defense system comprises a sensor device and a comprehensive control system, wherein the sensordevice comprises a frequency spectrum detection device, a radar detection device and photoelectric detection device; and the comprehensive control system is connected with the frequency spectrum detection device, the radar detection device and the photoelectric detection device and is used for receiving original signals of the frequency spectrum detection device, the radar detection device and the photoelectric detection device, carrying out comprehensive processing on the original signals, carrying out target detection and identification through an artificial intelligence algorithm and sending out corresponding defense measures according to target detection and identification results. According to the low-altitude defense system, the comprehensive control system is used for carrying outcomprehensive processing on the original signals of the frequency spectrum detection device, the radar detection device and the photoelectric detection device, and the frequency spectrum detection device, the radar detection device and the photoelectric detection device are only used as terminal sensors; the low-altitude defense system is easy to expand, reconfigurable, wide in application range and flexible in configuration; and false alarms and missed alarms, caused by target detection through a single means, are reduced, so that a black flying unmanned aerial vehicle is effectively countered.

Description

technical field [0001] The invention relates to the field of low-altitude defense, in particular to an artificial intelligence-based low-altitude defense system. Background technique [0002] Such as figure 1 As shown, in the existing low-altitude defense system, the spectrum detection equipment is responsible for spectrum monitoring and direction finding. First, it collects electromagnetic signals within a certain frequency range, and then performs feature analysis and detection for UAV remote control and image transmission signals. If the detection finds an electromagnetic signal that meets the characteristics, it is considered to be a drone, and the radio direction finding is performed on the electromagnetic signal to obtain the position of the radiation source of the electromagnetic signal, and finally the detection result and direction finding position information are sent to the control and display system The radar detection equipment uses the electromagnetic signal e...

AI Technical Summary

Problems solved by technology

[0003] In the existing low-altitude defense system, radar detection equipment, spectrum detection equipment, photoelectric detection equipment and other sensor equipment work independently, and the system has a single function and is not easy to expand

In addition, the single-sensor device performs target detection and recognition, and uses the existing feature template to classify the extracted target feature information. When the environment changes, it cannot adapt to pattern recognition, resulting in poor classification effect, low detection rate and recognition rate, and difficult get the desired effect
