摘要
针对目标识别和探测等领域对目标时域响应快速获取的需求,提出了一种基于扫频雷达散射截面积(radar cross section,RCS)数据的目标时域响应转换方法。首先根据入射信号的波形参数设计相匹配的扫频参数,然后利用频域电磁散射建模或测试等手段获取目标的宽带散射特性,最后通过对扫频数据进行变换域信号处理,获取目标的时域响应。对典型圆柱组合体目标进行时域响应仿真实验,仿真结果表明,基于传统频域建模方法及扫频测量系统,所提方法能够实现任意波形入射信号下目标时域响应的快速获取。
Aiming at the requirements of rapid time-domain response acquisition in fields such as target recognition and detection,a method for target time-domain echo conversion based on frequency-sweeping radar cross section(RCS)data was presented.Firstly,corresponding frequency-sweeping parameters were designed according to the waveform parameters of the incident signal.Then,the frequency-domain modeling or testing of the electromagnetic scattering was employed to obtain the broadband scattering characteristics of targets.Finally,the time-domain response of targets was acquired by processing the frequency-sweeping RCS data.The simulation test was implemented to calculate the time-domain echo of a typical cylinder combination.The simulation results show that,based on the traditional frequency-domain modeling method and frequency-sweeping system,the proposed method can realize rapidly acquire the time-domain response of targets under arbitrary waveform incident signals.
