Semi-active laser seeker performance test method and apparatus thereof

Abstract

The invention discloses a semi-active laser seeker performance test method and an apparatus thereof. A technical scheme is characterized in that a laser target simulator tightly sleeves a tested seeker and the two are connected to a control cabinet through two cables respectively; the control cabinet contains a direct current power supply, an alternating current power supply, a master control computer, a relay control panel and a signal acquisition plate; the master control computer controls the relay control panel, the signal acquisition plate and the laser target simulator through a communication interface; the relay control panel and the signal acquisition plate are connected to the tested seeker respectively; the signal acquisition plate includes an A/D acquisition circuit, a communication control loop and a memory; the laser target simulator mainly includes a pulse-type laser diode, a signal generation module, a controller and the like; the signal generation module generates a pulse signal of a specific code at an assignment direction according to an instruction requirement; and the pulse-type laser diode generates a laser which is used to simulate a reflection echo signal of a target and excite the tested seeker so that performance detection is completed.

Description

[0001] Technical field: [0002] The invention relates to a laser testing method and equipment, in particular to a semi-active laser seeker performance testing method and device. [0003] Background technique: [0004] Semi-active laser-guided products typically require periodic testing to determine if their seeker is working properly. The test of the seeker is usually a qualitative test, that is, to determine whether the seeker has a corresponding response voltage to the targets in the four directions of "up, down, left, and right". Currently, the laser irradiator of the semi-active laser-guided bomb is located in the On the airborne platform, there is a big difference between the full elastic performance test on the ground and the actual combat environment, which in turn affects the performance judgment of the seeker. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide ...
