Abstract

The invention belongs to the technical field of laser target simulation, and relates to a laser moving target simulator. The laser moving target simulator is characterized in that a laser is used forradiating laser light; through a movement control module, energy is adjusted by an energy adjusting unit, and the light spot size is adjusted by a light spot adjusting unit; a light spot movement unitis used for adjusting the direction and the pitching angle of the light spot, outputting the laser light and projecting the laser light to a laser light scattering screen to form diffuse reflection laser light; and an optical collimation subsystem is used for collimating the diffuse reflection laser light and providing approximately infinitely far laser light excitation for a tested laser light guiding head. According to the wide-range, high-precision, high-speed, high-stability and high-response-speed laser moving target simulator, a reliable testing platform is provided for guiding head developing and performance testing, the problems that a traditional laser moving target simulator is narrow in energy change range, poor in linearity, low in light spot position precision, speed precision and light spot adjusting precision and the like are solved, product development and finalization are accelerated, and a great effect is achieved in the stages of designing, developing, commissioningand the like of a laser guided weapon system.

Description

technical field

[0001] The application belongs to the key technical field of high-precision and large-range laser moving target simulation, and relates to a laser moving target simulator, in particular to a high-precision, high-speed, high-stability and wide-range laser motion control module. Background technique

[0002] In the traditional model development process of laser-guided weapons, there are two serious problems that hinder the development of laser-guided weapons: the long development cycle of new technologies and the very limited traditional laboratory tests. In order to solve these two problems, it is necessary to establish a laser moving target simulation system (laser moving target simulator) to provide a reliable test platform for the development and performance testing of the seeker. Different stages such as prototype development and commissioning have a big role.

[0003] The laser moving target simulation system is the core of the hardware-in-the-loop simul...
