Ocean Clutter Iteration Cancellation Based on Extended Prony Algorithm
摘要
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 the offing background with two cancellation methods. By simulations it is proved that the effect of the method , ocean clutter iteration cancellation based on exdended Prony algorithm,is of effectiveness , which elevates the ship target detection performance with CIT in the offing hackground.关键词
