Abstract

Peculiarities of using space-time multi-frequency signals, formed by the transmitting active phased antenna array of the radar with superfast electronic scanning of angular coordinate are considered. Connection of the signals’ structure, their spectral and correlation properties with the parameter of multi-frequency modulation in the antenna array and its characteristics is discovered. It is shown that the use of spaced in frequency complex partial signals in the elements of transmitting array and the selection of the corresponding modulation laws provides synthesis (restoration) of directional properties of the transmitting antenna with minimal losses and low side lobes in the angular observation sector in the receiver by means of correlation processing of the echoed signals.
