摘要:
A method and system for presence detection within a detection volume delimited by an inner radius and an outer radius using microwave radiation. The outer radius of the detection volume is controlled by selecting the length of a first pulse controlling the transmit interval of a microwave transmitter and by selecting the length of a third pulse controlling the receive interval of a microwave receiver. The inner radius of the detection volume is controlled through selecting the length of a second pulse defining a predetermined time period between the first pulse and the third pulse.
