Space-based detecting and tracking imaging system testing device and testing method

Abstract

The invention provides a space-based detecting and tracking imaging system testing device and a testing method. The testing device comprises an air-floating platform (1), a high-precision movable target (4), a collimator loaded on the high-precision movable target for providing an infinite-far shooting object, and an angular velocity measuring device mounted on the air-floating platform (1); the space-based detecting and tracking imaging system as a system to be tested (5) is coaxially and fixedly mounted on a rotating platform of the air-floating platform (1), and a triaxial intersection point of the system to be tested is a vertex of a rotating light cone of the high-precision movable target (4); the rotating platform is attached to a pull wire along a tangential direction, and hangs a weight (2) by being winded with a fixed pulley, and tangential force is applied to the rotating platform by the dead weight of the weight. The invention realizes the testing of a plurality of important performance indexes of the space-based detecting and tracking imaging system, and thus further adjustment and optimization, guarantees product quality, and ensures the quality of the space-based detecting and tracking imaging system and the normal operation on rails.

Description

technical field [0001] The invention belongs to space target detection and tracking imaging technology, in particular to a measurement method and testing device for the performance parameters of such equipment as space target detection and tracking imaging. Background technique [0002] The function of the space-based (space-borne) detection and tracking imaging system is to accurately detect and track and image important space targets, and determine the mission, size, shape and Important target characteristics such as orbital parameters; classify and distribute target characteristic data. The development of space-based detection and tracking imaging systems is conducive to improving my country's ability to monitor, track and identify space targets, and to enhance real-time perception of space battlefield situations and space offensive and defensive capabilities. In addition, the development of space-based detection and tracking imaging systems is also conducive to the deve...

Problems solved by technology

The movement of any part on the satellite and the change of the movement state will bring disturbance to the satellite platform, that is, there will be torque output to the satellite platform. If the torque is large or lasts for a long time, it will affect the attitude control of the satellite, especially in this If it is greater than the adjustment and control capabilities of the satellite attitude control system, it will affect the normal operation of the satellite. This phenomenon is very terrible.
