| 摘 要： | 对于发射信号为无载波高频窄脉冲的探地雷达，导出了层状有损介质表面电磁响应的积分方程算法。首先，利用滤波算法计算层状介质频率域响应方程的汉克尔变换，然后通过傅氏变换计算时间域响应，实现探地雷达观测波形的正演模拟。该算法可在频率域对多种发射波形、阵列天线成相控阵天线发射情况下的电磁响应进行处理和计算。经过模型试算，并与其他算法的结果进行比较，证明该算法是正确的。

| Abstract: | For a suriace detection radar with its emission signal as noload wave high Irequency narrow pulse. an integral e-quation algorithm of layered lossy medium surface electromagnetic response is derived . Forward modeling of wave forms detected with a surface detection radar is implemented by calculating Hankel transformation of the response equation in layered medium frequency domain with filtration algorithm through the calculation of time domain response with FFT algorithm. The algorithm would be used to handle and calculate various mission waveforms and the electromagnetic response under the conditions of emitting from array antenna and phased array antenna. The algorithm is verified to be correct through trial calculation with a model and compared with other calculating result. |
