Paper Abstract

The paper presents basic overview of processing techniques used in radars working with nonuniform sampling of echo signals. In the pulsed or periodically modulated wave radars the sampling of the return signal is inherently connected with the pulse (or modulation) repetition period. Thus, if the period is time-varying, the sampling moments of Doppler echo signal are nonuniformly spaced. The nonuniform sampling enables the use of special processing that makes it possible, under certain conditions, to deduce some signal properties in the frequency range above Nyquist limit.
