Ground penetrating radar antenna radiation performance evaluation method and evaluation system

The invention discloses a method and a system for evaluating the radiation performance of a ground penetrating radar antenna. The method comprises the following steps: step 1, bandwidth testing; and step 2, radiation performance testing. According to the evaluation method disclosed by the invention, testing is carried out in the time domain, huge workload of testing in the frequency domain is avoided, simple time domain parameters are used for analysis, and the radiation performance of the antenna can be analyzed more conveniently and accurately; a test waveform is a differential waveform of a pulse emission signal, and a display result is an intuitive time domain reflection or scattering echo and is easy to interpret. 本发明公开了一种探地雷达天线辐射性能评价方法和系统，该方法包括如下步骤：步骤1，带宽测试：步骤2，辐射性能测试。本发明所公开的评价方法，在时域进行测试，避免了在频域测试的庞大工作量，用简单的时域参量进行分析，可以更便捷、准确的分析天线的辐射性能；测试波形为脉冲发射信号的微分波形，显示结果为直观的时域反射或散射回波，易于判读。
