The Research On Laser Searching And Tracking Of Bidirectional RVD

With the rapid development of modern science and technology,laser is applied broadly than ever for the advantages of high directivity,high frequency,high energy and high coherence.laser is not essentially attenuated in the special transmission.It is predominate to make tracker actual connection with targeter by laser.The work has been perfoming in America,Japan,western Europe and Russia.There are many ways to realize Rendezvous and Docking.Laser navigation and laser communication could be accomplished by laser searching and tracking way,many datas ,such as the relative distanceand and velocity are provided by the laser radar of tracker simultaneously.so it is very important to rearch the laser searching and tracking in spacial RVD.In chapter1,the research condition and develop tendency are firstly analysed,especially in the point of laser application.Then we tell about the origin ,object and contents of the subject.Then we discussed the consist and function of multifunctional laser equipment basis of chapter1. Laser systems consisting of antenna, searching and tracking ,measurement,communication and emissive are studied.In chapter2,the gordian techniques of laser searching and tracking system in multifunctional equipment,such as laser radar,communication and navigation compact technology,optimizational laser searching and tracking technology,angle error acquisition technology,double moding controlling technology,decouple technology and simplify technology to bi-directional traching are analyzed.In chapter3,the sensitivity,angle resolution,influence factors and getting ways to angle erro signal are mainly rearched.we designed optical front-end,receiver, signal processing system and CCD photography system.the scheme frame are drawn.In chapter4,we discussed the indicator of movement,selected the device model,build the mathematical model,designed the searching and tracking loop.At last,we bring forwardd the controlling project,that is woked in 2 modes.In chapter5,we build the mathematical model of laser searching and tracking,we also introduced the function,usage and simulating result.In chapter6,the rearching work and main viewpoint are generalized.
