Signal processing method, radar system, and vehicle

A radar system, comprising:

• at least M transmit antennas, at least N receive antennas, a transmitter coupled to the at least M transmit antennas, a receiver coupled to the at least N receive antennas, and at least one processing module, wherein
• the transmitter is configured to sequentially transmit signals according to a first transmission sequence through the M transmit antennas, wherein the first transmission sequence is different from a sequence that is formed by arranging the M transmit antennas based on spatial locations thereof;
• the receiver is configured to receive, through the N receive antennas, echo signals formed by reflection of the transmitted signals off of a target, wherein M and N are positive integers, and M is greater than 2;
• and
• the at least one processing module is configured to measure a parameter of the target based on the echo signals.

A vehicle, comprising:

• a radar system comprising at least M transmit antennas, at least N receive antennas, a transmitter coupled to the at least M transmit antennas, a receiver coupled to the at least N receive antennas, and at least one processor, wherein
• the transmitter is configured to sequentially transmit signals according to a first transmission sequence through the M transmit antennas, wherein the first transmission sequence is different from a sequence that is formed by arranging the M transmit antennas based on spatial locations thereof;
• the receiver is configured to receive, through the N receive antennas, echo signals formed by reflection of the transmitted signals off of a target, wherein M and N are positive integers, and M is greater than 2;
• and
• the at least one processor is configured to measure a parameter of the target based on the echo signals.
