1. A radar detection device, comprising:
a radar device, comprising a plurality of antennas to transmit and receive radar signals;
a signal processing device, coupled to the radar device, and determining that a target object is in a first area of a detection area or in a second area of the detection area according to the radar signals received by the radar device; and
a processor, coupled to the radar device and the signal processing device,
wherein when the signal processing device determines that the target object is in the first area, the signal processing device performs the activity detection to determine whether a fall event of the target object has occurred,
wherein when the signal processing device determines that the target object is in the second area, the signal processing device performs the vital-sign detection to determine whether a vital-sign of the target object is abnormal,
wherein when the signal processing device determines that the target object is in the second area, the signal processing device further determines whether a movement amount of the target object in the second area is greater than a threshold, wherein when the movement amount of the target object in the second area is greater than the threshold, the signal processing device of the radar detection device switches to perform the activity detection from the vital-sign detection.
