Abstract

A radar scanning system and a scanning method are provided. The processing unit of the radar scanning system is configured to perform the following steps in a scanning round: sending a control signal to cause the radar unit to scan a plurality of predetermined fields of view of the radar unit, and recording, in response to finding a tracked object in the predetermined fields of view through scanning, coordinates of each tracked object and setting a preferential field of view, based on the coordinates of the each tracked object; and creating a scan list, setting, in response to finding the tracked object in the predetermined fields of view, the scan list to include the preferential field of view, and controlling, based on the scan list and a scanning and processing policy, the radar unit to perform scanning.

Claims20

Dependent claims

A radar scanning system, comprising:

a radar unit for generating a radio frequency signal, radiating the radio frequency signal to a field of view of the radar unit, and receiving a feedback signal to scan the field of view;
and
a processing unit for performing the following steps in a scanning round:
(a) sending a control signal to cause the radar unit to scan a plurality of predetermined fields of view of the radar unit, recording, in response to finding at least one tracked object in the predetermined fields of view through scanning, coordinates of each of the at least one tracked object, and setting at least one preferential field of view based on the coordinates of the each of the at least one tracked object;
and
(b) creating a scan list, setting, in response to finding the at least one tracked object in the predetermined fields of view through scanning, the scan list to comprise the at least one preferential field of view, and controlling, based on the scan list and a scanning and processing policy, the radar unit to perform scanning.
