We describe a new active sonar processor that obtains simultaneously fine range and Doppler resolution by fusing data from sequentially transmitted linear frequency-modulated (LFM) and CW waveforms. We model the received data as returns from a small number of point-reflectors and fuse returns from the two waveforms using a novel formulation that assumes common amplitude and random phase (CARP). We demonstrate the method using simulated data.
