Paper Abstract

The paper presents a novel method for NLFM radar signal instantaneous frequency estimation. Up to now there are only a few limited reports in this field. The method involves combined short-time Fourier transform and IF curve smoothing in time – frequency plane. The algorithm performs a fine estimation of instantaneous frequency of noise buried signals up to -3 dB. Due to FFT and simple filtering application, there is no high computational load needed. Simulation results indicate that the algorithm is robust and outperforms well-known phase differentiation method.
