基于频域校正的快速长时间积累算法
A Fast Long-Time Accumulation Algorithm Based on Frequency-Domain Correction
摘要
Abstract
In order to solve range migration and Doppler walk caused by target motion during long-time coherent integration period, a novel fast algorithm based on frequency-domain correction is proposed. The Radon-Ambiguity transformation is utilized to estimate the acceleration and the acceleration compen-sation factor is constructed to correct range bend and Doppler walk.Then the relevance coefficient be-tween the two echoes is used to estimate the velocity, and the velocity compensation factor is constructed to correct range walk.The simulation results prove the effectiveness of the proposed algorithm.关键词
