    Estimation of inter-pulse phase/frequency stepping parameters in electronic intelligence systems
    (IEEE, 2018) Alp, Y. K.; Gök, Gökhan
    In this work, a new method for estimating the modulation parameters of radar pulses which make interpulse phase/frequency stepping for pulse compression. Proposed method first applies special filters, which magnifies phase/frequency stepping instants, to the instantaneous phase of the measured radar pulse. Then, Robust Least Squares (RobLS) algorithm is utilized for anomaly detection. The local maximum of the detected anomaly points provides the high resolution estimates of the phase/frequency stepping instants. Extensive experiments conducted on synthetic data sets for different SNR (Signal-to-Noise Ratio) levels and phase/frequency stepping values show that proposed method can successfully estimate phase/frequency stepping instants.
