Design And Implementation Of Anti-photoelectric Detection System Based On "Cat-eye Effect"

The single-soldier combat unit equipment in the world today,high performance,high ratio of optic photoelectric photoelectric equipment such as small arms fire control system greatly improved the individual's combat ability,can be hidden to efficiently perform kill each other fighters,interfere with each other military operations and other operations.Research and development,therefore,an efficient detection optics,photoelectric sight photoelectric equipment such as portable photoelectric detection equipment,implement effective against under complex environment,such as stealth,is the modern warfare the objective demand of reconnaissance perception and equipment development.Based on the phenomenon of "cat-eye effect" in optical and photoelectric sights,this paper proposes an equipment research scheme of anti-photoelectric detection system which USES laser active detection technology to generate the echo signal of "cat-eye effect" and identify the target,so as to detect the enemy's hidden optical and photoelectric equipment.The specific work and research results are as follows:1.In the formation mechanism of "cat-eye effect" phenomenon description,on the basis of analyzing the using active laser detection target launch technology principle,and based on this concept of equipment of photoelectric aiming system "cat-eye effect" phenomenon existing in the implementation of the theoretical analysis,proves that the incident to the optical system with the "cat-eye effect" phenomenon in any light,its reflex the light after a"cat-eye" system will be in strict accordance with the original light back;The characteristics of laser echo and the maximum detection range of "cat-eye effect" targets are analyzed.2.This paper proposes a technical parameters can meet this topic research scheme of the photoelectric detection system,and an anti-photoelectric detection system is designed based on this scheme,and the development of optical subsystem,laser detection module,control and processing module,power supply and display module is realized.The software of"cat-eye effect" target recognition image processing is developed.3.A method of difference calculation is developed for the collected passive and active images,tag binary difference image centroid coordinates different connected domain,statistics of the series of main passive at the centroid coordinates grayscale image frequency information,and then the possible target area for circular degree,judgment and the "cat-eye effect" the algorithm of target identification.4.Through the field test of the prototype and the analysis of the experimental results,the research scheme and design of the system can meet the technical index requirements of the subject,and it is feasible for production.At the same time,the influence of laser power change on the phenomenon of "cat-eye effect" was verified,which laid a foundation for the future research and development of the subject.
