Signal processing method and device, radar, medium, program product and terminal

A non-transitory computer readable storage medium storing therein a computer program or instructions, which, when executed by a processor, causes the processor to implement a signal processing method, the method comprising:

• transmitting, during a first transmit cycle, a first detection signal through M transmit channels;
• transmitting, during a second transmit cycle that is different from the first transmit cycle, a second detection signal through m1 transmit channels in the M transmit channels, wherein m1<M, m1 and M are positive integers;
• and
• processing a first echo signal and a second echo signal to determine a correspondence between the first echo signal and the M transmit channels;
• wherein the first echo signal and the second echo signal are signals generated after the first detection signal and the second detection signal are reflected by a target, respectively;
• wherein transmitting the first detection signal through the M transmit channels comprises:
• transmitting the first detection signal with pulses phase-stepped by

A radar, comprising a transceiver and a processor, wherein the transceiver comprises:

• at least one antenna;
• and
• M transmit channels, wherein the transceiver is configured to transmit a first detection signal through the M transmit channels during a first transmit cycle and a second detection signal through m1 transmit channels in the M transmit channels during a second transmit cycle that is different from the first transmit cycle, and to receive one or both of a first echo signal and a second echo signal;
• wherein m1<M, m1 and M are positive integers;
• and
• wherein the processor is configured to process the first echo signal and the second echo signal to determine a correspondence between the first echo signal and the M transmit channels;
• wherein the first echo signal and the second echo signal are signals generated after the first detection signal and the second detection signal are reflected by a target, respectively;
• wherein the transceiver is configured to transmit the first detection signal through the M transmit channels by:
• transmitting the first detection signal with pulses phase-stepped by
