摘要
对雷达信号的时延估计技术进行研究是雷达信号处理的一项重要任务,本文首先介绍了典型的时差估计方法,然后结合我们的研究针对雷达信号的时差估计作出了一种改进的算法,它将相位相关技术应用到广义相关时差估计算法中,通过仿真验证了该算法的有效性,并得到了一些有益的结论。
Time delay-estimation of radar signal is an important task in radar signal processing. This paper first introduces typical time delay estimation methods. Then based on our research, an improved algorithm for time delay estimation of radar signal is proposed, It applying phase correlation to broad sense correlation delay estimation algorithm. Simulation results show the effectiveness of the proposed algorithm and some conclusions are drawn availability.
