摘　　要：为了解决传统探地雷达集成难度大的问题,提出一种基于先进软件无线电技术的全新探地雷达设计方案。通过对ADRV9002的特性和开发方式进行研究,设计了能够满足探地需求的跳频信号。为增强雷达检测和分辨率能力,同时考虑到发射的信号需要满足正交性,根据两种不同机制的跳频信号分别设计了以时间分集和频率分集两种不同MIMO收发方式。根据实验结果对比可知,ADRV9002的跳频速度优于AD936X,可以为探地雷达系统设计提供更为快捷的设计思路。In order to solve the difficulty of traditional GPR integration,a new GPR design scheme based on advanced software radio technology is proposed.By studying the characteristics and development mode of ADRV9002,the frequency hopping signal which can meet the requirements of ground exploration is designed.In order to enhance the detection and resolution ability of radar,and considering that the transmitted signal needs to meet the orthogonality,two different MIMO receiving and receiving modes with time diversity and frequency diversity are designed according to the frequency-hopping signals of two different mechanisms.According to the experimental results,the frequency hopping speed of ADRV9002 is better than that of AD936X,which can provide a faster design idea for GPR system design.
