Analysis of detection efficiency of signals discretely coded in frequency in the presence of passive clutter
V. Ya. Plyokin, Nguen Thang Khyng
An expression is derived for the signal-to-noise ratio, in terms of power, at the output of the accumulator of the burst of signals discretely coded in frequency, and of composite signals discretely coded in frequency, against the passive clutter background. Several quality indices, characterizing the suppression of passive clutter in suppression devices, are defined. The detection characteristics are calculated for the case when the passive clutter is suppressed with the aid of different suppression devices. The calculation forms a basis for estimating the efficiency of detection of such signals.
