HUMAN BODY DETECTING DEVICE
Document Type and Number:
Japanese Patent JP2002071824
Kind Code:
A
Abstract:
To accurately detect a position of a human body in human body detection using a microwave sensor.
The position of the human body is accurately detected by using a Doppler effect of the microwave sensor and an effect by size of reflection. To be specific, in this human body detecting device using the microwave sensor, one radio wave transmitting part of the microwave sensor and two radio wave receiving parts of the microwave sensor are provided, and a microwave transmitted from the radio wave transmitting part is received by one of the radio wave receiving parts as a Doppler signal for moving body detection and by the other as size of a reflected wave of the microwave.
