通过频域合成和复图像合成，实现一维信号的带宽合成，从而提高回波信号距离向的分辨率。(Through the frequency domain synthesis and complex image synthesis, realize a d signal bandwidth synthesis, so as to improve the echo signal to the resolution of the distance. )

1、根据干扰总功率要求，在PSK调制信号带宽内产生单音干扰和多音干扰信号，并叠加到产生的信号源上。 2、将收到干扰的信号进行频率搬移到基带，然后通过匹配滤波器以及解调过程得到信息，统计误码率并与真实信息的解调误码率进行对比，评估音频干扰对PSK信号的干扰效果。 (1, according to the total power requirement of interference generated tone signal interference and multi-tone interference in the PSK modulated signal bandwidth, and superimposed on the signal generated by the source. 2, the received interference signal to a baseband frequency shift, and the information obtained by the matched filter and a demodulation process, statistical error rate BER and the true information demodulation comparison, evaluation of the PSK signal, audio interference interference effects.)
