Abstract
Noise radars represent a rapidly growing research topic owing to numerous advantages over the conventional radars. This study proposes a method for strong non-stationary jammer suppression in noise radar systems. The corrupted received signal is divided into non-overlapping segments so that the instantaneous frequency (IF) of the jammer can be approximated by a parabola within each segment. To that end, an adaptive recursive procedure is proposed. The procedure uses the polynomial-phase transform to estimate the parabola coefficients. The jammer suppression is done for each segment separately. The simulations, performed for various types of FM interferences, prove the effectiveness of the proposed method even for highly non-stationary jammers with non-polynomial phase.
