Abstract :
An airborne pulse Doppler radar depends on a combination of range selectivity and velocity selectivity to detect targets in ground clutter. At a sufficiently high bandwidth the phenomenon of range bin migration occurs, precluding the use of conventional Doppler processing. The product of the range-rate and the coherent integration period exceeds the range resolution. A fast algorithm is introduced. It performs coherent integration/Doppler filtering while explicitly accounting for range bin migration. The fast algorithm is based on an integration along a slanted line in the 2-D frequency domain.
