Comparison of several methods for high speed detection target with narrow bandwidth

A new method dealing with high speed target (HST) detection in pulse-Doppler (PD) radar is proposed. By utilizing Keystone Transform (KT) and linear range walk rectification, the range walk can be removed completely. The method is also compared with the Hough Transform (HT) and Complex Radon Transform (CRT). The simulated data validates the method and the analysis.
