Photoelectric aiming system look-down tracking test method and test device for implementing the method

Abstract

The invention discloses a photoelectric aiming system look-down tracking test method and a test device for implementing the method. The test device includes a two-dimensional turntable, a collimator is mounted on the two-dimensional turntable, and an installation part for fixing the position of the photoelectric aiming system is arranged above the collimator, and the installation part is assembled on the frame. The invention realizes the relative movement between the collimator and the photoelectric aiming system by driving the collimator to move with a two-dimensional turntable, thereby simulating the movement of the radio and television aiming system relative to the target source. During this process, the parallel light emitted by the collimator The light source is always facing upwards, so that the photoelectric sighting system above the collimator will not have a blind spot in the field of view. Especially when it is necessary to test the downward viewing performance of the photoelectric sighting system for the target directly below, the photoelectric sighting system can be placed directly on the collimator. At this time, the collimator and the photoelectric sighting system will not be interfered by the two-dimensional turntable, thus increasing the scope of the photoelectric sighting system's downward-looking tracking performance test.

Description

technical field [0001] The invention relates to a photoelectric aiming system look-down tracking test method and a test device for implementing the method. Background technique [0002] At present, after combat aircraft such as transport planes, bombers, drones, and helicopters launch laser-guided weapons, the airborne photoelectric targeting system needs to keep track of the target and provide irradiation guidance for laser-guided weapons. Since most laser-guided weapons have no power, and the flying speed of the weapons is lower than that of the carrier aircraft after delivery, there is often a need for the photoelectric targeting system to look down and track the target. In this way, when testing the tracking performance of the photoelectric sighting system, it is necessary to test the down-looking tracking performance of the photoelectric sighting system. The downward-looking tracking performance test process of the existing photoelectric sighting system is as follows: ...

Problems solved by technology

However, when it is necessary to use the cursor of the collimator to simulate the target directly below the photoelectric sighting system, the receiving end of the photoelectric sighting system will face vertically downward. The cursor of the collimator cannot be observed, so the existing test device can only realize the tracking performance test within a limited pitch range. The occlusion of the target cannot keep track of the target, and there is a blind spot in the test
