The invention relates to a composite axis tracking and aiming performance testing device and method. The device comprises a supporting frame, an optical simulation target source, a main rotating shaft, a sub-rotating shaft, wherein the optical simulation target source is used for emitting a light beam; the main rotating shaft is installed on the supporting frame, and the main rotating shaft can rotate relative to the supporting frame; the sub-rotating shaft is mounted on the main rotating shaft, the sub-rotating shaft can rotate relative to the main rotating shaft, the sub-rotating shaft is provided with a sub-rotating table, the sub-rotating table is provided with a semi-transparent and semi-reflective mirror and a reflecting mirror which are arranged at an interval, the semi-transparent and semi-reflective mirror is used for transmitting part of the light beam emitted by the optical simulation target source to form an emergent light beam approximately parallel to the sub-rotating shaft, and the semi-transparent and semi-reflective mirror is used for reflecting part of the light beam emitted by the optical simulation target source to the reflecting mirror, and enabling the reflecting mirror to reflect to form an emergent light beam which is approximately parallel to the sub-rotating shaft. Simultaneous measurement can be conducted on a coarse tracking detector and a fine tracking detector.
Description
technical field [0001] The invention relates to the technical field of compound axis tracking performance testing, in particular to a compound axis tracking targeting performance testing device and a testing method thereof. Background technique [0002] At present, the composite axis tracking and aiming system adopts two-level tracking methods, coarse and fine, in which the coarse tracking system realizes azimuth 0° to 360° and pitch 0° to 90° to capture, detect and track targets in a large range through a two-dimensional turntable; the fine tracking system uses high The bandwidth fast mirror further suppresses the residual error of the coarse tracking system and realizes high-precision target tracking. Since the tracking angle accuracy of the compound axis tracking and aiming system reaches the order of μrad, it is necessary to equip a corresponding high-precision tracking and aiming performance test device during the factory acceptance test.
