In article are considered heat direction
finders, working on the atmospheric background. Defining characteristics of such
systems are the maximal range of detection (selection) at
as much as possible wide angular floor of optical system. In such devices
the removed thermal target will have the dot image borrowing on the screen of
1-2 pixels. Such mark to the operator for notice is difficultly. Therefore in
work is considered the question of algorithm creation of the bidimentional
spatial filter which capable automatically (without participation of the
operator) to define coordinates of the dot thermal target.
The theoretical and
practical importance of work consists in use of a plenty of the experimental
data received on faculty of radio engineering in the military academy of ad in
the course of the long period of time with use of specially developed techniques
on the basis of which the mathematical modelling is carry out. The analysis of
preliminary mathematical modelling results has confirmed working capacity of
offered algorithm of the spatial filtration.
Novelty of the decision
of the considered scientific problem consists in use of differences of spatial
spectra of the "dotty" target and extensional background, and originality of the
decision consists in the way of spectra estimation through coefficient of mutual
Scientific results of
work can be used at creation of functioning algorithms of video processors
of the air targets detection having a
wide field of vision.
