摘　　要：采用时域电场积分方程和互易原理相结合的方法,探讨了已知接收信号的情况下,脉冲发送信号的波形,并研究了视距和非视距两种传播路径对脉冲收发信号的影响。在分析中,脉冲波形和天线几何形状可以任意。分别以蝴蝶形天线和超宽带槽式天线为例,并将计算结果与已知接收脉冲信号进行了比较。它们之间良好的一致性说明了所提方法的正确性和有效性。The time domain electric field integral equation （TD-EFIE） in conjunction with the reciprocity principle is applied to synthesize the transmitting impulse signals on condition that the receiving signals have already been known. In addition, the effects of light-of-sight （LOS） and non-light-of sight （NLOS） propagation paths on the transmitting and receiving impulse signals are also discussed. In the analysis, impulse waveform and the shape of the antenna are arbitrarily given. The bowtie antennas and ultra-wide band （UWB） slot antennas are taken as examples and the computed results are compared with the known receiving impulse signals. The good agreement between them shows the correctness and effectiveness of the method proposed.
