摘要

摘要: 空時(shí)自適應(yīng)處理是衛(wèi)星導(dǎo)航抗干擾的有效方法。但在高動(dòng)態(tài)環(huán)境下，干擾來(lái)向動(dòng)態(tài)變化，干擾很容易移出常規(guī)自適應(yīng)抗干擾算法所形成的窄零陷，導(dǎo)致算法失效。常用的解決辦法是加寬零陷。該文從干擾來(lái)向變化的統(tǒng)計(jì)模型出發(fā)，提出一種基于拉普拉斯分布的空時(shí)加寬零陷算法，該算法能在干擾方向形成較寬的零陷。并且考慮到空時(shí)處理將增加算法的計(jì)算復(fù)雜度，該文將新的空時(shí)加寬零陷算法與多級(jí)維納濾波器相結(jié)合，給出一種基于空時(shí)降維處理的加寬零陷算法。新算法能有效降低算法復(fù)雜度，并能在小快拍下得到更好的性能。仿真結(jié)果表明新算法的有效性。

Abstract: Space-Time Adaptive Processing (STAP) is effective to suppress wideband jammers in satellite navigation system. But in high-dynamic environment, the conventional STAP anti-jamming algorithms are invalid since jammers may easily move out of the array pattern null so that it can not be suppressed. In this paper, a new method of STAP null-widen is deduced based on Laplace distribution model of the changing interference DOA in high-dynamic environment. This method can broaden the width of nulls. But because of using of STAP, the amount of computation is increased significantly, a STAP null-widen method based on reduced-dimension Multistage Wiener Filters (MWF) is given in this paper. The effectiveness of the new method is proved in simulation part.
