METHOD AND SYSTEM FOR DETECTING GEOLOGICAL STRUCTURE OF EXTRATERRESTRIAL SOLID CELESTIAL BODY BY EMPLOYING SINGLE TRANSMITTING AND MULTI-RECEIVING RADAR

摘要

A method for detecting the geological structure extraterrestrial solid celestial body by employing a single-transmitting and multi-receiving radar. The method comprises: completing the detections of structure and thickness distribution of various geological stratification of extraterrestrial solid celestial body by employing a single transmitting and multi-receiving work module; inverting information of dielectric constant and depth etc. of various geological stratification by using the electromagnetic wave propagation theory. The method has an advantage of high reliability. Also disclosed is a carrier-less ultra-wideband pulse radar system for detecting the geological structure extraterrestrial solid celestial body. The system employs two detecting channels comprising a CH1 detecting channel and a CH2 detecting channel. The CH1 channel for detecting a rock structure of the celestial body works in a HF/VHF wave band, the detecting depth is greater than 100 meters, the resolution is a meter grade; The CH2 detecting channel for detecting a shallow soil structure of the celestial body works in a UHF wave band, the detecting depth is greater than 30 meters, the resolution is smaller than 30 centimeters. Cooperative work and mutual complement between the two detecting channels can ensure the accuracy and reliability of detecting work.
