Miniature multimode deep ground penetrating radar

Deep ground penetrating radar, as its name says, is able to image the deep buried objects with high resolution. It becomes an important tool for human to know the underground world. In this paper a stepped frequency deep penetrating radar system has been developed. This miniature system is designed for three operation modes: Mode 1 is fast measurement, real-time data storage, off-line data analysis and imaging. Mode 2 is wireless real-time detection and imaging. Mode 3 is on-line real-time detection and imaging. Three modes can be switched flexibly for different working platform, such as low altitude aerocraft, planetary rover or lander, UAV (unmanned aerial vehicle), remote control vehicle and robot, vehicles or just hand holding. The miniature radar host is designed based on the embedded frame to satisfy the multi-modes operation condition including light-weight, small volume and low power consumption.
