PROCEDE D'ESTIMATION DE LA FREQUENCE DOPPLER NON AMBIGUE D'UNE CIBLE MOBILE, NOTAMMENT MARINE, ET RADAR METTANT EN OEUVRE LE PROCEDE

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).
