Abstract :
The intellectual adaptive system of detection of low-sized air objects on a background radar clutter from the ground level environment based on overlapping of the power and spectral analysis with adaptation of detection parameters to statistics and to the average interference spectrum in a vicinity of an analyzed resolution cell is offered. Such a combined digital-logic analysis of a spectral pattern of a preliminary detection proves to be rather effective and, as show results of experimental studies, allows to lower a false alarm probability on one-two order. At the same time, it is significant, that the functional scheme of examined detector doesn´t contain complicated digital and logic operations. In one´s turn, it provides relative simplicity of the scheme realization in the low- and medium-range radars and also in the perspective radars with the digital spectral analysis of the signals.
