Abstract

The invention provides a precise self-adaptive height determining method for an ultra-wideband proximity detector and the detector thereof. The method includes the following steps that S1, a receiver clock circuit provides a time sequence signal; S2, a receiving sampling pulse circuit and a preorder sampling pulse circuit respectively generate pulses and transmit the pulses to a sampling pulse synthesis circuit; S3, a correlator circuit receiving antenna incoming signal generated by the sampling pulse synthesis circuit is processed; S4, after a correlator circuit removes interference from an input signal, a receiving signal and a preorder waveform are obtained; S5, a target reflection coefficient estimation module calculates a reflection coefficient according to the received signal and transmits the reflection coefficient to a baseband dynamic gain control module; S6, the baseband dynamic gain control module applies gain to the incoming signal and then transmits the incoming signal to a signal processing module; and S7, after the signal processing module judges the burst height consistency, a judgment output module outputs a result. According to the precise self-adaptive height determining method for the ultra-wideband proximity detector and the detector thereof, the target reflection coefficient is obtained by comparing received signal preorder waveform information with actually measured data, so that the problem that the burst height judgment consistency is difficult to guarantee is solved.

Description

technical field [0001] The invention relates to the technical field of radio proximity detection, in particular to an ultra-wideband proximity detection method for precise self-adaptive height determination and a detector thereof. Background technique [0002] The proximity fuze is a fuze that senses the existence, distance and direction of the target according to the characteristics of the target or the characteristics of the environment. Formerly known as a non-triggering fuze. Proximity fuzes can be used for anti-personnel bombs, armor-piercing bombs, anti-personnel / armor-piercing dual-purpose bombs, explosive bombs, assault bombs, and barrier-breaking bombs, as well as special bombs such as incendiary bombs and smoke bombs. . When it is used in anti-personnel, armor-piercing, anti-injury / armor-piercing dual-purpose bombs, the overall effectiveness is significantly improved. Proximity fuze is a kind of fuze that can best reflect the advanced nature of ammunition, and i...
