An Azimuth Measurement Algorithm for Mechanically Rotating Pulse Doppler Radars.

Abstract

For a mechanically rotating pulse Doppler radar having only a single main beam, an algorithm is presented that obtains an estimate of a target's 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 radar's main beam. (KAR) P. 2
