Abstract
A method of radar ranging comprises transmitting a digitally-modulated signal comprising successively in time, for each sequence in a plurality N of sequences, a plurality M+1 of repeats of said sequence, wherein each said sequence consists of a plurality Lc of digitally-modulated chips, wherein at least one sequence in the plurality of sequences is different from another sequence in said plurality of sequences; receiving a version of the digitally-modulated signal reflected scattered by one or more physical targets; for each sequence in the plurality of sequences, performing a preliminary target estimation; and using each said preliminary target estimation for all sequences in the plurality of sequences, performing a final target estimation.
