Problems solved by technology
However, because the two axes of the turntable and the two axes of the radar tracking and aiming are not collinear, the angle simulated by the turntable cannot effectively simulate the relative motion relationship between the stars, which in turn causes the radar tracking and aiming to produce two-axis cross-coupling measurement errors

Embodiment Construction
[0065] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.
[0066]The radar is composed of a mechanism controller, a signal processing component, an antenna and a driving mechanism. The relay computer is connected to the signal processing component. The signal processing component processes the original signal measured by the radar and sends it to the relay computer; The antenna motion command is given to the mechanism controller; the mechanism controller controls the antenna motion according to the received command. After the antenna receives the microwave signal, it is first processed by the high-frequency receiving component fixed on the mechanism side, and then sent to the signal processing component through the waveguide. After the signal processing component is comprehensively processed, it will generate the required angle and distance data. These angle and distance...

Description
technical field [0001] The invention relates to high-precision ground verification in the technical field of space relative measurement, in particular to a radar tracking and aiming high-precision ground test error compensation system and method. Background technique [0002] Microwave radar is a tracking and aiming device used in space to search, capture, and track non-cooperative targets. It continuously measures the relative angle and distance information between satellites and provides them to the GNC subsystem for relative navigation calculations. It is the basis for autonomous relative navigation. Base. [0003] The radar tracking and aiming high-precision ground verification system uses the turntable to rotate an opposite angle to simulate the relative motion angle between the stars. However, since the two axes of the turntable and the two axes of radar tracking and aiming are not collinear, the simulated angle of the turntable cannot effectively simulate the relativ...
