摘　　要：利用亚ns级脉冲源及取样示波器,采用双接收天线分别接收回波信号与触发信号的形式,减少了系统的时基抖动,提高了系统稳定度和灵敏度;在复杂测试背景中实现了目标散射测量,获取了目标超宽带RCS;与标准体的理论RCS值相比,测量结果误差小于1dB,说明了该瞬态散射测试系统及方法的有效性。Synchronized collecting of echo signal and the triggor signal is achieved by the dual-receiving antenna using sub-ns pulse source and sampling oscilloscope. It reduces jitter and improves stability and sensitivity of system and wideband RCS distribution of the target is obtained. Compared to theoretical RCS of standard targets, the error of the measured data is less than 1 dB. It illustrates the validlity of the test system and method of transient scattering.
