Original Abstract Submitted
A system includes first and second transmitters, a receiver, a processor, and a non-transitory computer-readable medium. The processor causes the first and second transmitters to transmit first and second chirp signals, respectively. The second chirp signal has an in-band frequency offset in fast-time and slow-time and at least one of a carrier frequency offset in slow-time and a phase offset relative to the first chirp signal. The processor causes the receiver to receive reflections of the chirp signals off of objects in the environment, resulting in a received radar signal. The processor performs a range fast Fourier transform (FFT) and a Doppler FFT on the received radar data to obtain a range-Doppler-antenna data cube. The processor performs range-Doppler alignment of reflections of the first and second chirp signals and phase correction based on the phase offset. The processor then performs digital beamforming.
