基于太阳风暴的月球内部结构探测方法研究

Research on lunar interior structure detection method based on solar storm

月球探测是我国太空探测的重要任务,月球内部结构探测是其中一个重要的研究方向.以瞬变电磁法(transient electromagnetic methods,TEM)为基础,提出了一种基于太阳风暴的月球内部结构探测方法.该方法利用太阳风暴产生的磁场跃变作为使月球内部产生极化的探测源,在太阳风暴作用下,月球内部介质极化产生感应磁场,通过对该磁场信号的探测和处理获得月球内部结构信息.对磁场跃变在月球内部的感应磁场信号进行正演模拟计算,并通过仿真实验验证了该探测方法的有效性和正演算法的正确性,为后续研究打下基础.

The lunar exploration is an important task of Chinese space exploration,and the lunar interior structure exploration is one of the important research directions.Based on transient electromagnetic method,this paper presents the lunar interior structure exploration based on the solar storm.In this exploration method,magnetic field jump generated by solar storms is used as the detection source to generate polarization in the lunar interior.At the moment of the magnetic field transition,the internal medium polarization of the lunar generates an induced magnetic field,and the internal structure information of the lunar can be obtained through the detection and processing of the magnetic field signal.In this paper,the forward simulation of the induced magnetic field signal is carried out,and the simulation experiment can verify the validity of the detection method and the correctness of the forward algorithm,which lays a foundation for the subsequent research.
