摘　　要：为了探索探地雷达技术应用于块根类农作物收获的可行性,对探地雷达探测木薯深度信号的可行性进行了理论分析和试验测试。设计了试验思路与测试方法,分别选取不同频率的天线,从不同的方向进行探测,得出一系列木薯的物理特征图像和木薯波形信号;通过对比记录到的图像及信号波形等资料,可以得出无论仪器是从不同方向行走测试还是以不同频率探测,对比结果均有较好的稳定性和同一性。选用不同的天线、行走不同的路线,得到了不同探测精度和分辨率的相似结果,验证了使用探地雷达技术作为木薯收获时的木薯深度信号采集的可行性,为实现木薯收获自动化奠定了技术基础。In order to explore the feasibility of applying ground penetrating radar technology to harvest root crops, the feasibility of detecting cassava depth signals by ground penetrating radar was theoretically analyzed and experimentally tested. The experimental ideas and testing methods are designed. Different frequency antennas are selected and detected from different directions. A series of cassava physical characteristic images and cassava waveform signals are obtained. By comparing the recorded images and signal waveforms, it can be concluded that the comparison results have good stability and identity whether the instrument is walking in different directions or detecting at different frequencies. Using different antennas and walking different routes, similar results with different detection accuracy and resolution are obtained, which verifies the use of ground penetrating radar technology.
