摘要
为了同时对付有源和无源干扰,需要同时采用旁瓣相消(SLC)和动目标显示(MTI)技术,且 SLC 一般都在 MTI 处理之前实现。本文分析了 SLC 对 MTI 产生影响的原因,并将其分解为理想权值和权值噪声两种不同性质的影响,它们分别等效于展宽了杂波的频谱和产生了附加噪声。文章还提出了各种不同因素的作用。最后,提出了一种简单有效地补偿 SLC 对 MTI 影响的方法。
For simultaneously dealing with both active and passive interference,it is needed to use side- lobe canceller (SLC)and moving target indicator (MTI) together ,and usually the SLC is realized before the MTI. The cause for the effect of the SLC on MTI is analyzed,which may be decomposed into two different kinds,i,e.ideal weight and weight noise.They are equivalent to extention of the spectrum of clutter and production of additive noise.The influence of different factors is also proposed.Finally,a simple and efficient method to compensate the effect of SLC on MTI is proposed.
