Ground penetrating radar system design method for detecting internal structure of small celestial body

A ground penetrating radar system design method for detecting an internal structure of a small celestial body is characterized in that a low-frequency detection part and a high-frequency detection part are designed, detection frequency and bandwidth are determined according to target detection depth and detection resolution requirements by building an electronics box, and detection time sequence parameters and minimum radar transmitting power corresponding to low frequency and high frequency are respectively designed; the design of the low-frequency antenna and the high-frequency antenna arranged outside the ground penetrating radar system is completed, deep penetration and high resolution are both considered, the size is small, the weight is light, the reliability is high, and the antenna can be expanded to be applied to detection of internal structures of other celestial bodies in deep space detection. 一种用于小天体内部结构探测的探地雷达系统设计方法，设计有低频探测部分及高频探测部分，通过搭建电子学箱，根据目标探测深度、探测分辨率需求确定探测频率及带宽，分别设计探测时序参数及低频、高频对应的最小雷达发射功率，完
