Селекция движущихся целей в сверхширокополосной радиолокационной станции

Abstract

The article describes the principle of implementation of an UWB sounding signal for short range radar. The comparative analysis of UWB signals classification variants is made. A mathematical model of the formation of an ultrashort radio pulse from a video pulse is presented. The use of ultrashort radio pulses does not have difficulties in technical implementation and makes it possible to achieve high stability of the parameters of the sounding signal. The options for estimating speeds for UWB systems are considered. The method for moving-target indication and their separation from the underlying surface for UWB radars is proposed. The method uses coherent integration with subsequent spectral analysis based on Fast Fourier Transformation. Experimental studies of the proposed method of moving-target indication are made. The results of experiments prove the proposed method efficiency.
