冲激雷达实验系统与测量数据处理技术

本文介绍一种冲激雷达实验系统。它是设置在微波暗室内的全空间实验系统,天线、录取电路和数据处理器是专门设计的,能录取各种目标的回波数据,给出实时处理结果。文中讨论了数据处理技术,提出用规则化方法求解目标冲激响应、估计AR模型参数,给出了实际结果,表明该算法的有效性。测量了涂覆RAM目标的回波,对比分析结果证实了冲激雷达具有良好的反隐身能力。

Experimental Impulse Radar System and Data Processing

An experimental impulse radar system is presented. This system, known as free space system, islocated in a microwave anechoic chamber. The transmitting and receiving antennas, A/D converter, con-trolling board and data processor are specially designed. This system can receive echoes of many kinds oftargets and obtain the results in real time. In this paper, we also discussed the data processing techniqueand present a regularization means to solve the impulse response, estimate AR model parameter and givethe real data processing results. All these results verify the efficiency of this system. In the last, we in-troduce the procedure of measuring the echo signal of RAM-covered target. Through the comparison,we verify that impulse radars have the ability of anti-stealth targets.
