Research On Performance Testing Technology For Laser Seeker

Laser precision-guided bombs,missiles and bombs and other weapons plays an extremely important role in the high-tech local war.Seeker,as the core component of laser guidance weapon,in order to guarantee the performance of target detection and tracking,detection and fault diagnosis and location must be done before the system put into use.This paper foucs on the seeker perforance test,which is a critical problem,especially taking the active and semi active laser seeker as the research object,making theoretical analysis and method demonstration of the performance test technology.First of all,this paper expounds the background of topic research significance,then briefly introduces the related concepts of precision guidance,laser guidance technology,and the study of laser guidance weapon system at home and abroad,and summarizes the status quo of the application;Secondly,this paper analyzes the the performance characteristics of homing guidance,driving beam guidance and command guidance and other laser guidance technology,studied the main composition,classification and development trend of current laser guidance weapon;Again,the work principle,structure and function of the laser seeker and anti-interference methods are demonstrated,then make an analysis of the laser seeker signal acquisition method for target location and tracking loop system detection and the principle of the gyro tracking;Finally,this paper design the laser seeker comprehensive performance and energy characteristics of hardware-in-the-loop simulation test system,solve the threshold of detection sensitivity,the calibration of micro energy laser light source and other technical problems,then set a laser seeker automatic assessment system,and describe the working mode and hardware of the system in detail.The research results of this paper may further improve the reliability and accuracy of laser guidance weapon,and will play a positive role in promoting the operational application and technological innovation of our laser guidance weapon.
