摘要
A method and a system for detecting geological structure of an extraterrestrial solid planet by using a single-transmitter and multiple-receiver (STMR) radar are provided. According to the method, the detection of thickness distribution and geological structure of each geological layer on the extraterrestrial solid planet can be obtained by using a single-transmitter and multiple-receiver mode. Then information of the dielectric coefficients and the depth of the respective geological layer can be calculated accurately. Further, in the system, there are two detection channels, in which a first detection channel CH1 operates in a HF/VHF band for detecting geological structure of rocks on the extraterrestrial solid planet with a depth of detection over 100 meters and a depth resolution of several meters, and a second detection channel CH2 operates in a UHF band for detecting geological structure of regolith on the extraterrestrial solid planet with a depths of over 30 meters and a depth resolution less than 30cm. These two detection channels can cooperate with each other, ensuring accuracy and reliability of the detection.
