Abstract

The invention discloses a passive type electrostatic detection system based on signal differential detection and a method thereof. The method includes the following steps: S1. calculating and obtaining induced charge distribution on a detector pole plate and induced voltage on the detector pole plate by utilizing an integral equation-moment method algorithm; S2. canceling out the influence of a charged cloud and a ground object by differential signals of the induced voltage of two groups of detectors, and retaining a response of a target charge; and S3. solving and calculating to obtain orientation, pitch, distance, speed, and amount of charge parameters of a charged target based on a differential detection algorithm of main and auxiliary pole plates, and according to the induced voltage of the detector pole plate. The system can effectively eliminate a charged background, such as environment interference of a cloud layer, and has high precision in detecting orientation and pitch angles of a target.

Description

technical field

[0001] The invention belongs to the technical field of passive static detection, and in particular relates to a passive static detection system based on signal differential detection and a method thereof. 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 detector electrode. 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 anti-environmental interference (such as charged cloud interference, ground object interference, and electromagnetic interference).

[0003] Traditional electrostatic detection methods mostly use experimental means to directly measure the vol...
