This paper considers the problem of estimating motion parameters a low-observable high-speed maneuvering target with high-order motions, where target’s complex motions will result in range migration (RM) and Doppler frequency (DFM) effects within observation time interval, which significantly affect radar performance. Based on Hough transform (HT) polynomial Chirplet (PCT), novel method for par...

one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...
