| 摘 要： | 在分析海杂波产生机理的基础上,提出了一种基于扩展Prony算法的海杂波循环对消法,在传统的海杂波循环对消法中用扩展Prony方法对频率进行估计,从而提高对正弦信号的频率、幅度、相位的估算精度。在相同数据点数、信噪比的条件下,运用2种对消法对短相干积累条件下的海面背景舰船目标检测情况进行仿真分析。仿真实验验证了基于扩展Prony算法的海杂波循环对消法检测舰船目标的有效性,提高了短相干积累条件下的海面背景下的舰船目标检测性能。

| Abstract: | On the basis of analysis of mechanism of ocean clutter production,an ocean clutter iteration cancellation method based on extended Prony algorithm was proposed,which uses the extended Prony algorithm to estimate the frequency in the conventional cancellation method,which can be adopted to provide more accurate estimation of frequency,amplitude,phase of sinusoidal.Under conditions of same sample numbers and SNRs,simulations are used for the ship target detection with short coherent integration time(CIT) in t... |
