Analog system and analog method of dynamic electromagnetic scattering characteristics in space object convergence

Abstract

The invention relates to an analog system and an analog method of dynamic electromagnetic scattering characteristics in space object convergence, and is used for testing experiment of dynamic electromagnetic scattering characteristics in space object convergence under ground conditions. The system includes a radio-frequency system, an instrument automatic control system, a scanning support and a control system that are in circuit connection as well as an object hanging system. The analog method is that an interval is set for each stepping to test the amplitude and phase of the back wave of the object during the convergence, so as to extract Doppler characteristic signals. The scanning support and the object hanging system can be combined in a moving way in the laboratory to analog the convergence movement of the space object, so as to perform the analog testing research of the object dynamic electromagnetic scattering characteristics during the space convergence, as a result, the scattering characteristic data of the required object can be obtained, and the urgent demand of the autonomous convergence technology research of the object can be satisfied.

Description

technical field [0001] The invention relates to the technical field of measurement of target and environment electromagnetic scattering characteristics, in particular to a simulation system and method for dynamic electromagnetic scattering characteristics of space target rendezvous. Background technique [0002] At present, there is no measured data of the electromagnetic scattering characteristics of targets under space rendezvous conditions, which cannot meet the needs of the development of space target autonomous rendezvous technology. It is very difficult and costly to measure the electromagnetic scattering characteristics of targets under space rendezvous conditions. It not only consumes a lot of money and manpower, but also is limited by space and time, so it is impossible to obtain a large amount of required measured data safely and reliably. Contents of the invention [0003] The present invention provides a simulation system and simulation method for the dynamic e...
