基于Keystone变换的雷达增程设计研究
A Study on Design about Increase Radar Range Based on Keystone Transform
摘要
Abstract
Space debris target,long distance space target and new stealth target often exceeded the range of the equipped radar for their characteristics of small radar cross section,long distance and high speed.Consequently,low signal-noise ratio (SNR) and the range migration problem often occurred in the conventional radar echo signal.To solve these problems,a compensation method based on Keystone transform was proposed for range alignment,and the equipped radar is reconstructed corresponsively by using bypass method,which doesn't change its original performance,then the pulses coherent integration was used to improve SNR.As a result,the comprehensive capability of the equipped radar system was enhanced.Simulation and experiment results show that the proposed method is applicable,therefore it has a strong engineering application value.关键词
