Solving Doppler ambiguity by Doppler sensitive pulse compression using multi-carrier waveform

A processing technique, which exploits the structure of the multi-carrier signal to obtain range and radial velocity information from the echo signal, is proposed. The novel processing technique executes the Doppler matched filter bank digitally, and solves the ambiguity in the radial velocity measurements in one train of multi-carrier pulses as a result of Doppler sidelobes of the ambiguity function being lower. The processing technique, being independent of the phase coding on the multiple carriers, enables integration of communication and radar waveforms.
