Target burst height consistency judgment method based on radio proximity detection technology

Abstract

The invention discloses a target burst height consistency judgment method based on a radio proximity detection technology. The target burst height consistency judgment method comprises the following steps of S1, setting each radio signal extension set; S2, enabling each radio signal extension set to transmit and receive a radio signal, and estimating a reflection coefficient of a target through a target reflection coefficient estimation module; S3, processing the signals by using a baseband dynamic gain control module, processing the signals by using a signal processing module, and transmitting the processed signals to a radio receiving switchboard; S4, enabling the radio receiving switchboard to receive each baseband target echo signal, and deducing burst height information through an ASIC chip; and S5, using a data integration comparison module of the ASIC chip to carry out joint comparison on the burst height information, eliminating information with overlarge deviation, and judging whether the target burst heights are consistent or not. According to the method, the target is detected by utilizing multi-angle radio transmitting, and then all information is jointly calculated and compared, so that the judgment accuracy of burst height consistency is improved.

Problems solved by technology

[0003] However, for targets with different reflection coefficients, due to the uncertainty of the echo intensity, it is difficult to guarantee the consistency of the output height judgment of the ultra-wideband radio proximity detector based on the existing scheme. Affected by different external factors, etc., it is easy to cause deviations in the judgment of bombing height information, thus affecting the accuracy of bombing height information and the judgment of bombing height consistency
