Abstract

The invention discloses a passive electrostatic detection system based on signal differential detection and a method thereof, comprising: S1, calculating the induced charge distribution on the detector plate and the induction charge on the detector plate by using the integral equation-moment method algorithm Voltage; S2, offset the influence of charged clouds and ground objects through the differential signals of the induced voltages of the two sets of detectors, and retain the response of the target charge; S3, based on the differential detection algorithm of the main and secondary plates, according to the induced voltage on the detector plates , solve and calculate the azimuth, pitch, distance, speed and charged quantity parameters of the charged target. The invention can effectively eliminate the charged background, such as the environmental interference of the cloud layer, and has high precision in detecting the azimuth and elevation angle of the target.

Description

Technical field [0001] The invention belongs to the technical field of passive electrostatic detection, and specifically relates to a passive electrostatic detection system and method based on signal differential detection. Background technique [0002] The principle of passive electrostatic detection is electrostatic induction, which is a detection method to detect the relevant information of the target through the phenomenon that the electrostatic field of the target generates an induced charge on the electrode of the detector. It has the characteristics of good concealment, anti-stealth, and anti-electronic interference, making it an effective way to challenge electronic countermeasures and stealth threats. The disadvantage is that it has poor resistance to environmental interference (such as charged cloud interference, ground interference, electromagnetic interference). [0003] Traditional electrostatic detection methods mostly use experimental methods to directly measure the ...
