Abstract
The disclosure relates to an echo simulation method and device for solving incapability of moon-base radar simulation in the prior art. The method includes steps of: calculating a lunar orbit parameter according lunar ephemeris data; setting a radar system parameter according to lunar orbit parameter and an observation requirement; determining a central time moment of the echo simulation and a beam irradiation position corresponding to the central time moment according to the lunar ephemeris data; setting a point target within a range of the beam irradiation position corresponding to the central time moment of the echo simulation, wherein the point target is a target irradiated during the echo simulation; and acquiring the echo data of the point target based on the radar system parameter. The echo simulation method and device achieves the echo simulation of the moon-base radar.
Description
technical field [0001] The present disclosure relates to the technical field of radar simulation, and in particular, to an echo simulation method and device. Background technique [0002] With the gradual deepening of research in the field of natural sciences, human beings have gradually realized the existence of "solid tides", and discovered that the large-scale dynamic changes in the long-term natural evolution of the earth directly affect the climate and environment of the earth. At present, the SAR (Synthetic Aperture Radar, Synthetic Aperture Radar) system cannot meet the measurement scale requirements at the crustal plate level due to various reasons, and considering the performance characteristics of artificial satellites, it is not difficult to find The idea of improving the radar observation capability is not the most reasonable way to solve the problem. There must be a new form of carrier platform to break through the bottleneck faced by the artificial satellite ...
