Design and Test of Intelligent Diffuse Reflector False Target Jamming System

Abstract

Diffuse reflector is a kind of false target which is widely used in laser angle deception system. Because of its protective ability, it has become an important part of laser angle deception system aiming at laser guided weapons. At present, there are some problems in the application of decoy target, such as complex deployment process and low jamming efficiency, which restrict the performance of equipment. Based on the requirements of equipment development, this paper proposes a design of jamming system based on Intelligent diffuse reflector false target, builds a complete hardware test platform and establishes the model. The angle and attitude error of the diffuse reflector, the response time of the system and the energy density of the reflected laser are measured in the direction of 0°,30° and 45° commonly used in the equipment deployment. The test results show that the real-time control angle error of the intelligent diffuse reflector false target jamming system is within 1° and the average response time of the system is less than 10s, and the average value of the reflected energy density is 4.72 respectively×10-15J/mm2, 4.30×10-15J/mm2 and 4.15×2 J/mm2 interference distance is 2046m, 2007m and 1976m. It can be seen that the diffuse reflection board can improve the real-time jamming effect of the false target by adjusting the diffuse reflection board and the false target. It provides a new idea for the development of laser countermeasure equipment.
