A radar detection system and a radar field of view (FOV) direction adjustment method are provided. A processing unit of the radar detection system performs the following steps in one scanning round: obtaining at least one cluster of a current frame and a current status and a next status of each cluster based on digital feedback signals; and determining a displacement, determining, based on the current status of a tracked cluster in the at least one cluster and the displacement, whether the tracked cluster is located on an edge of a current FOV of a radar unit, and sending a 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 FOV, to adjust an FOV direction of the radar unit.

A data pre-processing method is provided. By using an energy distribution parameter set obtained through beamforming scanning, a signal-to-noise ratio of a signal can be improved and a detection range region can be automatically generated, thereby improving an object tracking effect. An exercise vital sign detection radar is also provided.

Data pre-processing method and exercise vital sign detection radar

A non-contact exercise vital sign detection method is provided. At least one candidate position having an energy intensity exceeding an energy threshold is pre-selected from a vibration frequency map, and a position having a vibration frequency meeting a vital sign parameter range is then selected as a target position from the at least one candidate position. Accordingly, phase data obtained according to the target position facilitates accurate detection of a vital sign parameter of a subject.

A method for processing digital signals is provided. In the method, a plurality of digital signals corresponding to radar signals received by a receiving terminal are superposed, so as to reduce noise caused by environmental interference. Therefore, according to an output signal obtained after the superposition, accurate characterization information of a to-be-detected object can be obtained.
