Abstract

The present invention provides a method for accurate self-adaptive height determination of an ultra-wideband proximity detector and a detector thereof. The method includes: S1: a receiver clock circuit provides a timing signal; S2: a receiving sampling pulse circuit and a pre-sequence sampling pulse circuit The pulses are respectively generated and sent to the sampling pulse synthesis circuit; S3: The correlator circuit generated by the sampling pulse synthesis circuit receives the incoming signal from the antenna for processing; S4: The correlator circuit de-interferences the input signal to obtain the received signal and the preamble waveform; S5: The target reflection coefficient estimation module calculates the reflection coefficient according to the received signal and then transmits it to the baseband dynamic gain control module; S6: The baseband dynamic gain control module applies gain to the incoming signal and then transmits it to the signal processing module; S7: The signal processing module judges the explosion After high consistency, the decision output module outputs the result. The invention obtains the target reflection coefficient by comparing the pre-sequence waveform information of the received signal with the measured data, and solves the problem that it is difficult to guarantee the consistency of the bomb height judgment.

Description

technical field [0001] The invention relates to the technical field of radio proximity detection, in particular to a method for accurately self-adapting height determination of an ultra-wideband proximity detector and a detector thereof. Background technique [0002] The proximity fuze is a fuze that senses the presence, distance and direction of the target according to the characteristics of the target or the environment. Formerly known as a non-triggering fuze. Proximity fuzes can be used with main bombs such as anti-personnel bombs, armor-piercing bombs, anti-personnel / armor-piercing bombs, blasting bombs, attacking bombs and obstacle-breaking bombs, and can also be used with special bombs such as incendiary bombs and smoke bombs. . When used in anti-personnel bombs, armor-piercing bombs, and anti-personnel / armor-piercing dual-purpose bombs, the overall efficiency is significantly improved. Proximity fuze is a kind of fuze that can best reflect the advanced nature of a...
