Estimation of doppler centroid in DBS processing and its application in real-time SW on Forward Looking airborne radar

摘要

The estimation of the Doppler Centroid is a common digital signal processing step in Doppler Beam Sharpering (DBS) air-to-ground radar mode. Such a radar mode is commonly implemented for Forward Looking (in the direction of the aircraft longitudinal axis) Airborne Radar with scanning antenna, to generate a radar image with a cross-range resolution higher than the corresponding antenna real beam resolution.
