Research On Laser Tracking And Deception Jamming Demonstration System

With the rapid development of laser guided technology, more and morecountries are armed with all kinds of new type of laser guided weapons. In recentseveral regional wars, laser guided weapons behave very well at destroying themilitary goals, and they shot more than90percent. And the semi-active laser guidedweapons are the most widely used laser guided weapons. Lots of countries has beenactively developing countermeasures against the semi-active laser guided weaponsto protect their military goals. As laser angle deceptive jamming technology is animportant way to against the semi-active laser guided weapons, the study ofdeceptive jamming is necessary. The task of this article is study the laser angledeceptive jamming based on laser tracking system.This article introduces the related technology of laser deceptive jammingexperiment system. This article analyses the related technology of the laser trackingsystem for instance the laser encoding technique, the principles and classily of lasertracking, wave gating technique, etc. This article introduces the related technologyof the laser jamming system for instance the principles and classily of laserdeceptive jamming, the laser jamming technique, etc.This article designs the laser deceptive jamming experiment system, subsystembased on laser tracking and subsystem based on laser jamming. The laser trackingsystem uses the semi-active guided, four-quadrant detector tracking technique, etc.which includes pulse modulated circuit, amplifier circuit, stretch circuit, processor,signals processor, etc. The experiment indicates that it can realize the function ofreal time tracking. The laser deceptive jamming system uses the technology ofsynchronous transmitting deceptive jamming. This system includes amplifier circuit,photoelectric detector, laser, etc. The experiment indicates that it can producejamming laser.For the convenient of the experiment and shielding electromagnetic wave, thisarticle designed a two-dimension laser tracking system, which integrating opticalelement, laser tracking system, step-motor etc. And the search scope of this systemis adjustable. In order to verify the system performance, this article uses the He-Ne laser asthe orbit indicator doing the indoor experiment of the laser deceptive jammingsystem. The result indicates that: the semi-active laser guided system can realize thefunction of real-time laser tracking. And the tracking accuracy is approximate±0.05degrees. When the laser deceptive jamming system works, it can lead thetracking system tracking the fake target, and the act time is approximate100ns. Theexperiment reaches the expected goals.
