MIMO radar signals with doppler code multiplexing

Abstract

An integrated circuit may include K transmit circuits that output K transmit signals, where K is a non-zero integer and the K transmit signals are encoded using first Doppler code multiplexing. Moreover, the integrated circuit may include L receive circuits that provide L receive signals (which may correspond to the K transmit signals), where L is a non-zero integer and the L receive signals are encoded using second Doppler code multiplexing. Note that the first and/or the second Doppler code multiplexing may be different from Doppler division multiplexing. Furthermore, the first Doppler code multiplexing may include selectively Doppler shifting a kth transmit signal in the K transmit signals by nk bins between chirps in a frame, and the second Doppler code multiplexing may include selectively Doppler shifting an lth receive signal in the L transmit signals by n1 bins between the chirps in the frame.
