MIMO RADAR CODING FOR RESOLVING VELOCITY AMBIGUITY

摘要

An apparatus for resolving velocity ambiguity in a MIMO RADAR includes a plurality of transmit channels and a virtual channel. Each transmit channel includes a transmit antenna configured to transmit a plurality of chirps. Each chirp includes a frequency ramp of a transmit frequency of the respective transmit channel. Each transmit channel is orthogonal to another transmit channel and to a virtual transmit channel. A waveform generator is configured to generate a local oscillator (LO) signal for each transmit channel. A frequency offset circuit is configured to modify the LO signal of each transmit channel with a respective frequency offset to generate the respective transmit frequency.
