摘要
The method involves providing an error correction phase for correction of target distance and Doppler frequency. A direct Fourier transform is utilized for representing a spectrum representation of a signal from the error correction phase. A radar image of a target is acquired from ambiguous Doppler frequency. A rank of ambiguity is calculated for the radar image of the target, where the radar image is arranged with a high degree of focus, and the target is arranged with a center of gravity (C).
