一种改进的Keystone变换算法及其在微弱信号检测中的应用
An Improved Keystone Transform Algorithm for Dim Moving Target Detection
摘要
Abstract
Range migration often occurs when coherent accumulation time is long in conventional Pulsed Doppler （PD） radar. This will degrade the property of radar to detect dim moving targets. Key- stone transform is a commonly used method to correct range migration. On the basis of fast implementation of Keystone transform using Chirp-Z transform （CZT） , an improved algorithm is proposed in this paper, which has even lower complexity. Computer simulations and real data processing results are given to dem- onstrate the effectiveness of the proposed method.关键词
