Radar detection system and radar field of view direction adjustment method

A radar detection system, comprising:

• a radar unit, configured to generate a radio frequency signal, radiate the radio frequency signal, receive a feedback signal, and demodulate and digitalize the feedback signal to obtain a digital feedback signal;
• a pointing control unit, configured to adjust a field of view direction of the radar unit based on a control signal;
• and
• a processing unit, configured to perform the following steps in one scanning round:
• (a) obtaining at least one cluster of a current frame and a current status and a next status of each of the at least one cluster based on the digital feedback signal;
• and
• (b) determining a displacement, and determining the edge of the current field of view based on the displacement;
• and determining, based on the current status of a tracked cluster in the at least one cluster, whether the tracked cluster is located on an edge of a current field of view of the radar unit;
• and sending the control signal based on the next status of the tracked cluster in response to the tracked cluster being located on the edge of the current field of view, to adjust the field of view direction of the radar unit;
• wherein the displacement is a predetermined fixed quantity, the current status of each of the at least one cluster comprises a current coordinate position, and step (b) comprises:
• determining, based on the current coordinate position of the tracked cluster, whether the tracked cluster is located on the edge of the current field of view of the radar unit.
