Original Abstract
We know active and passive methods of a location. This article deals only with a passive location of dynamic targets. The passive optics location is suitable just for cracking of targets with mean velocity which is limited by the hardware basis. 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. Suggested method is dealing with the short-distance evaluation of targets. We suppose the application of three independent principles 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. Methods are based on direct evaluation of picture sequence by the help of the histogram and frequency spectrum. We find out the probability of unidentified moving object in pictures. If the probability reaches a setting value we will get a signal. The processing of dynamic pictures and their filtration are significant part of work. Static objects, background (trees, buildings) must be filtered off before. This filtration is being also done by means of the probability function. Probability distribution of an object position is gained from a sequence of more pictures.
