Thunder field detection system based on low-altitude ultra-wideband synthetic aperture radar

Abstract

The invention discloses a thunder field detection system based on a low-altitude ultra-wideband synthetic aperture radar. The thunder field detection system comprises a ground management and control part, a flight control part and a radar detection part, the ground management and control part sends a flight instruction and a detection instruction to the flight control part and the radar detection part after completing a thunder field detection plan, and the flight control part executes the flight instruction and plans a flight route for flight. And the radar detection part executes a detection instruction, performs RD imaging algorithm processing on a detection echo signal, and transmits the processed detection echo signal back to the upper computer of the ground management and control part for imaging and identification. The system has the beneficial effects that the flight control part and the radar detection part adopt an unmanned aerial vehicle as an airborne platform, and an upper computer of the ground management and control part plans a detection task and controls the airborne platform to complete thunder field detection work; non-contact, rapid and accurate detection and real-time imaging of the thunder field are realized, and the danger of thunder field detection operation is reduced.

Description

technical field [0001] The invention relates to a minefield detection method and system, in particular to a low-altitude ultra-wideband synthetic aperture radar minefield detection system suitable for minefield detection in complex terrain environment. Background technique [0002] The minefield detection can neither miss the report nor the false alarm rate is too high. [0003] Traditional mine detection methods include military dog ​​detection and manual detection. The types of mines left after the war are complex, and most minefields have a large time span. The ability is very limited; manual detection mostly uses individual hand-held mine detectors, which is not only dangerous but also extremely slow in detecting mines. With the development of science and technology, more and more mine detection methods have appeared, such as infrared imaging, X-ray detection, radio wave and ultrasonic detection, etc., but most of them have a high rate of missed detection or false alarm...

AI Technical Summary

Problems solved by technology

However, traditional ultra-wideband GPSAR needs to touch the ground for detection, which has low efficiency and poor safety, and is difficult to detect in the complex terrain environment of minefields; therefore, a low-altitude ultra-wideband synthetic aperture suitable for minefield detection in complex terrain environments is developed Radar minefield detection system is very necessary
