For a mechanically rotating pulse Doppler radar having only a single main beam, an algorithm is presented that obtains an estimate of a targets azimuth angle using echo data obtained over a single coherent dwell. By removing the clutter and then cross-correlating the target echoes with a stored replica of the antenna pattern, azimuth angle measurement accuracies can be obtained within a fraction of a beamwidth. A Monte Carlo simulation was performed to determine the measurement error as a function of Signal-to-Noise Ratio SNR and target angular location within the radars main beam. KAR P. 2
