Infrared scene sand table system for testing infrared seeker

Abstract

The invention relates to an infrared scene sand table system for testing an infrared seeker. The infrared scene sand table system consists of a target model, background models and temperature control and power supplying systems, wherein the target model contains a heating module, the surface of the target model is coated with infrared reflection paint of different reflection ratios, and the infrared reflection paint is used for simulating infrared reflection conditions of real materials; the surfaces of the background models are covered with simulation materials, which are used for simulating the real materials, and are sprayed with the infrared reflection paint for simulating the real materials, and the background models are used for simulating topographic and geomorphic forms below a flight path; the temperature control system consists of a heating rod, a digital temperature controller and a platinum resistance temperature measuring probe and is used for controlling the temperature of the heating module in the target model and carrying out temperature adjustment on the heating module according to simulation needs. The infrared scene sand table system provided by the invention has the characteristic of infrared texture and can be used for simulating targets and backgrounds below a missile flight path, so as to provide a realistic infrared scene for infrared seeker semi-physical simulation experiments.

Description

technical field [0001] The invention belongs to the field of optical semi-physical simulation testing, and relates to an infrared scene sand table system used for infrared seeker testing. Background technique [0002] Missile is the main weapon of modern warfare, and the seeker is one of the core components of the missile, which directly affects the guidance accuracy of the missile. Therefore, relevant experimental research on the seeker will help improve the accuracy of missile guidance and make the target strike more accurate. In the process of seeker test development, due to the lethality and destructive influence of the missile itself, coupled with the consideration of research costs, physical tests are not advisable. In order to understand the experimental data of the seeker, it is necessary to carry out Related simulation tests. At present, infrared target simulators are often used for simulation tests of infrared seekers. However, for supersonic and hypersonic missi...
