外辐射源雷达系统中的自适应旁瓣相消及其ADSP-TS101s实现

基于外辐射源的雷达系统中可以使用自适应天线旁瓣相消技术以消除直达波和多径杂波的影响。以外辐射源雷达信号处理系统为基础,首先讨论了自适应天线旁瓣相消的原理,结合实时信号处理机的设计,给出了一种基于ADSPTS101sTigerSHARCDSP平台实现自适应天线旁瓣相消的硬件设计方案和软件实现流程。外场实验数据给出的处理结果说明本文方案是有效的。

ADSP - TS101s Realization of Adaptive Antenna Side - lobe Cancellation in External Illuminators - based Radar System

Adaptive antenna sidelobe cancellation technique can be used to cancel direct wave and multipath clutter in continuous wave radar experimental system using external illuminator such as broadcast as transmitter.Based on such a radar experimental system,this paper firstly analyzes the principle of adaptive antenna sidelobe cancellation.Combined with the designing of a real time signal processing subsystem,this paper gives way for hardware design scheme and software realization flow scheme based on ADSPTS101s TigerSHARC DSP platform.It has been demonstrated by actually experiments results that the scheme presented here can be effectively applied to a real system.
