A Passive Optical Location with Limited Range

Original language description

This article deals with the passive location of dynamic targets. The aim of this work is to recognize plasma, particles etc. It is possible to propose such kind of evaluation methods which improve the capture probability markedly. We suppose the application of three independent principles of how to recognize an object in a scanned picture. These principles use similar stochastic functions in order to evaluate an object location by means of simple mathematical operations. The methods are based on directevaluation of picture sequence with the help of the histogram and frequency spectrum. We are trying to find out the probability of appearance of moving object in pictures. If the probability reaches a setting value, we will get a signal. The probabilitydistribution of an object position is gained from a sequence of more pictures.
