Infrared/radar composite seeker wire harness disturbance torque test and suppression method

Abstract

The invention relates to an infrared / radar composite seeker wire harness disturbance torque test and suppression method, and belongs to the technical field of missile guidance. A servo stabilization platform of a composite seeker is driven by a direct-current torque motor, and by comparing the magnitude of starting voltages before and after connection of composite seeker wire harnesses, the magnitude of the interference torque of the wire harnesses is represented by the magnitude of pressure difference. The testing method comprises the steps that under the neutral equilibrium state of the servo stabilization platform, the heading and pitching up-and-down movement pressure difference within 0.3 V is taken as a test condition, the starting voltages at the same position in the heading and pitching frame angle range are tested, and the difference between the two starting voltages is calculated, so that the wiring harness disturbance torque condition represented in a voltage form can be obtained. According to the method, the influence of the disturbance torque of the wiring harness of the servo stabilization platform can be reduced by controlling the distribution of cables and the minimum starting voltage of heading and pitching, and the isolation and tracking performance of the infrared / radar composite seeker are improved; and the method is simple to operate and control, and easy to industrialize.

Description

technical field [0001] The invention relates to an infrared / radar composite seeker wiring harness interference torque test and suppression method, which belongs to the technical field of missile guidance. Background technique [0002] With the development of science and technology, the offensive and defensive technologies of both sides in modern warfare are constantly upgraded, and the traditional single-mode seeker can no longer adapt to today's complex and harsh battlefield confrontation environment. Therefore, the multi-mode composite seeker that combines multiple detection modes has become the main development direction of today's weapons. The infrared / radar composite seeker has been widely studied at home and abroad because of its strong ability to resist harsh environments and interference, strong target detection and recognition capabilities, and high guidance accuracy. [0003] In the infrared / radar composite seeker structure and servo system, there are more lead-ou...

Problems solved by technology

[0004] At present, the interference torque of the wire harness is generally tested by a special lead torque measuring device, and the measuring device has a complex structure and cumbersome operation

Compensation is used to compensate the interference torque of the wire harness to eliminate the influence of the interference torque of the wire harness. In this method, it is difficult to establish a model of the wire harness interference torque, and it is difficult to achieve accurate compensation for the servo system, and it cannot be applied to infrared / radar composite guidance. In mass production where the interference torque of the head harness is divergent
