A method for radar detection and range-Doppler estimation

摘要

Pulse-Doppler radar is suitable for target detection and parameter estimation such as range and radial velocity. The signal processing, in this type of radars, is based on matched filter and discrete Fourier transform (DFT). Detection, measurement accuracy and good resolution require the transmission of a train of pulses, where each pulse is usually frequency modulated. In some cases, even few trains of pulses are required. In this paper, we use statistical framework for detection and parameter estimation. By using the proposed algorithm, we show that targets can be detected and resolved using a transmission of an unmodulated single pulse where other classical methods based on matched filter may fail.
