MULTIPLE-INPUT, MULTIPLE-OUTPUT RADAR SYSTEM WITH RANGE-DOPPLER CIRCULATING CHIRPS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310505 titled 'MULTIPLE-INPUT, MULTIPLE-OUTPUT RADAR SYSTEM WITH RANGE-DOPPLER CIRCULATING CHIRPS
The abstract of the patent application describes a system that utilizes two transmitters, a receiver, a processor, and a computer-readable medium to transmit chirp signals, receive reflections of these signals, and perform various signal processing techniques to obtain radar data.
- The system includes first and second transmitters, a receiver, a processor, and a computer-readable medium.
- The transmitters transmit first and second chirp signals, with the second chirp signal having specific frequency offsets and phase offsets relative to the first chirp signal.
- The receiver captures reflections of the chirp signals off objects in the environment, creating a received radar signal.
- The processor conducts range fast Fourier transform (FFT) and Doppler FFT on the radar data to generate a range-doppler-antenna data cube.
- Range-doppler alignment and phase correction are performed based on the offsets between the chirp signals.
- Digital beamforming is then carried out for further signal processing.

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.
