Provided are an intruding object detecting apparatus (a radio wave sensor) capable of setting an arbitrary detection region, an apparatus for setting the detection region and a setting processe. An intruding object detecting apparatusis installed in a corner of a room, a coordinate system is defined in which a location of the intruding object detecting apparatusis an origin thereof, and coordinates are a distance r from the intruding object detecting apparatus and a scanning angle &#x3b8; of a transmission antenna/reception antenna of the intruding object detecting apparatus, and a state corresponding to the coordinate system is stored (b) in a storage means; thereby enabling the detection regionof the intruding object detecting apparatus can be arbitrarily set. Moreover, the setting can be performed with ease using a reflector or a transmitter, or alternatively, using a setting apparatus constituted of the reflector and the transmitter, combined.

Intruding object detecting apparatus, and setting apparatus, setting process and setting confirmation process therefor

A signal receiver includes a superregenerative circuit for feeding back a part of an output signal to form part of an input signal through a feedback route to execute a superregeneration, a capacitance element disposed in the feedback route of the superregenerative circuit, a switch for switching the capacitance element, and a PLL circuit for generating a clock signal for switching the switch based on an output of the superregenerative circuit.
