一、引言雷达旁瓣自适应对消系统是Widrow等人提出的自适应理论的一个重要应用。由于这一技术对于抗干扰及最终实现自适应阵列天线有着重要的意义,有关这方面的文献甚多。在本文中,我们对具有N个环路,受到r个干扰源干扰时的自适应旁瓣对消系统的对消剩余进行了分析。遵循从特殊到一般的原则,我们首先从单环对消器出发,讨论了自适应旁瓣对消器的原理,然后给出了一般性的结论。二、单环自适应旁瓣对消器单环自适应旁瓣对消器的基本框图如图1—1所示。
I. INTRODUCTION The radar sidelobe adaptive cancellation system is an important application of adaptive theory proposed by Widrow et al. Since this technique is of great importance to anti-jamming and eventually realization of adaptive array antennas, there is a lot of literature on this. In this paper, we analyze the cancellation residual of an adaptive sidelobe cancellation system with N loops interfered by r interferers. Following the principle from the special to the general, we begin with the monocyclic canceller, discuss the principle of adaptive sidelobe canceller, and then give a general conclusion. Second, the single-loop adaptive sidelobe canceller Single-loop adaptive sidelobe canceller block diagram shown in Figure 1-1.
