Digital Signal Processing System Research Of Semi-active Laser Seeker

The exactitude guided weapon has been one of the most important shocking means inmodern information wars．The laser end guided weapon has turned to be the key equipment ineach country in recent years．The only practical and reliable technology which can applied inthis field is semi-active laser guided technology．It’s excellences are high blowing precision，simple structure and high anti-jamming capability．It is widely used in missiles, bombs,rockets, bombs on a variety of conventional weapons.．Firstly, the thesis simply introduces several methods of guidance which are themainstreams and compare to a conclusion, then focuses on the principle of laser-guided. Onthis basis, the paper put forward the data processing program of laser-guided systems and theoverall design concept of the signal processing is described.Secondly, several key hardware modules for signal processing are described, whichinclude AD data acquisition module, AGC module, DSP control module, and serialcommunication modules.Next, the paper elaborates the details of VC and MATLAB data calibration，through theanalyzing and comparing of test results and the curves, the results show that the calibrationsolutions designed meet the basic indicators of booking.At the end of the paper, a brief description of the system’s error and the feasibility of theprogram is given and some improvements is proposed.
