Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A clamping fixture for plug electrode, including an upper mold, a lower mold and at least one clamping guide block is provided. The lower mold and the upper mold can be separated from and combined with each other. The upper mold has at least one opening through which at least one plug electrode is inserted. The at least one clamping guide block is disposed between the upper mold and the lower mold for clamping and releasing the at least one plug electrode. The lower mold has an inclined surface. When the upper mold is combined with the lower mold, the upper mold pushes the clamping guide block to move toward the lower mold, and the clamping guide block is guided by the inclined surface to move for clamping the at least one plug electrode.
