All-direction localizer of pulsed optical sources

Abstract

There are many applications in which the direction to some pulsed optical sources have to be determined: pointing and tracking systems for laser based free-beam optical communications, laser writing systems, ECM and so on. A mathematical model of a localizer system intended for a laser warning system is developed based on the amplitude monopulse method. A linear transducer of the pulse energy into the time interval was used. The block diagram was designed and implemented based on general purpose devices and integrated circuits. The numerical results of the software simulation are presented. The system may be implemented using ASIC techniques and consequently it's performance, especially the angular precision, can increase.
