Receiving gain multistage regulation and control method and device based on ray tracing theory

The invention provides a receiving gain multistage regulation and control method and device based on a ray tracing theory, and relates to the technical field of receiving gain control. According to the method, motion attitude information of the high-dynamic aircraft is acquired in real time; based on a pre-constructed receiving gain regulation and control value and aircraft attitude grading mapping table, determining receiving gain regulation and control value grading according to the motion attitude information of the high-dynamic aircraft; selecting matched regulation and control parameters according to the classification of the received signal strength and the receiving gain regulation and control values, and carrying out rough regulation and control on the receiving gain of the aircraft; after rough receiving gain regulation and control, a digital-to-analog converter is used for collecting and receiving signals and carrying out energy detection, and fine regulation and control are carried out.
