Abstract
Embodiments are provided for a radar system including: an N number of transmit antennas; a chirp generator configured to produce linear chirp waveforms; an N number of phase shift keying (PSK) coders, each assigned a respective optimized transmitter code of a set of optimized transmitter codes, each optimized transmitter code of the set comprises a sequence of K code chips, each optimized transmitter code of the set is orthogonal to every other optimized transmitter code of the set, spectral analysis of a cross-correlation between any two optimized transmitter codes results in sidelobes no greater than a predetermined detection threshold, each PSK coder encodes K linear chirp waveforms according to the sequence of K code chips of the respective optimized transmitter code and produces a respective optimized coded chirp sequence, and each of the N transmit antennas outputs the respective optimized coded chirp sequence at the same time.
