Method and device for controlling infrared radiation characteristics of profiling bait

Abstract

The invention discloses a method and device for controlling the infrared radiation characteristics of profiling bait. The control method pre-stores the characteristic parameters of the target and the response device in the read-only memory module, and the CPU main control module continuously reads the pre-stored target in the ROM. The characteristic parameters and the real-time temperature of the inner surface of the profiling bait collected by the temperature feedback module, after internal comparison and calculation, intelligently select external output control commands, and the D / A module converts them to obtain voltage and current signals, which are amplified by the drive amplifier module 1. After the expansion process, it acts on the array of infrared radiation characteristic devices to change the surface emissivity and temperature, so as to realize the purpose of profiling decoys to interfere with enemy infrared detection and protect targets from the field of view of infrared guided missiles. Compared with traditional coating-type and burning-type infrared radiation characteristic control methods, the infrared radiation characteristic control method of the profiling bait proposed by the invention has the characteristics of high controllability, strong applicability and fast response speed.

Description

technical field [0001] The invention relates to novel infrared detection and infrared guidance technology, in particular to a method and device for controlling the infrared radiation characteristics of profiling decoys. Background technique [0002] With the continuous development of new infrared detection and infrared guidance technology, especially with the application of infrared imaging technology and spectral recognition technology, the survival of military targets in modern battlefields has become particularly severe. The passive jamming technology that the profiling decoy acts as a false target to interfere with the enemy's detection and guidance has been paid more and more attention by various countries. [0003] According to the existing data, the United States uses cloth materials to make an imaging decoy false target. By placing a heater at the gas filling port to heat the gas, the corresponding coating covering the surface can emit infrared radiation that simulat...

Problems solved by technology

The above two methods can adjust the infrared radiation characteristics of the surface of the profiling bait to a certain extent, but the controllability is not high and it is difficult to achieve precise adjustment

Domestic profiling baits are mostly made of specially manufactured rubber materials and metal blended fabrics, which have the advantages of target radar characteristics, high pressure bearing capacity, cheap cost and light weight, but poor infrared simulation capabilities

[0004] In addition, in the research of automatic control device for infrared radiation characteristics, Tang Guanglun and Wang Liwei et al. [4、5] The proposed control scheme by collecting target surface or background infrared radiation signals is widely used in the control of infrared radiation characteristics of ground targets, but it is difficult to collect target or background infrared radiation signals for space target camouflage profiling decoys. Therefore, the application is limited
