本文描述了实现次最佳自适应空间滤波器(即所谓旁瓣对消器“SLC”)的数字方法。自适应空间滤波技术的一个重要应用就是抑制或至少是减少雷达天线旁瓣所收到的空间分布的干扰。最近制造了一个多到6个付天线单元的实验系统,它是一个模拟旁瓣对消器的对应物。由于模拟旁瓣对消器已使用多年,并已进行过广泛研究,因此,可以很容易地对模拟系统和数字系统的能力作直接比较。同模拟系统一样,数 This article describes the digital method of implementing the suboptimal adaptive spatial filter (the so-called sidelobe canceller “SLC”). An important application of adaptive spatial filtering techniques is to suppress or at least reduce the spatial distribution of the received sidelobes of the radar antenna. More recently, an experimental system of up to six antenna elements has been made, which is a counterpart to simulating a sidelobe canceller. Since analog side lobe cancellers have been used for many years and have been extensively studied, it is easy to directly compare the capabilities of analog and digital systems. The same as the analog system, the number
