Monitor
First Claim
1. A monitoring apparatus for being installed on a vehicle, sending out a radio wave, then receiving a radio wave generated by reflection of the radio wave, and thereby detecting a target including a material body and/or a human body, said apparatus comprising:
- a transmission antenna section for sending out a radio wave having directivity of a range, or for sending out in different beam directions a radio wave having directivity of range narrower than said range;
a receiving antenna section for receiving in each different beam direction the radio wave transmitted by said transmission antenna section and then reflected by said target;
a transmission section of transmitting for said transmission antenna section a signal to be sent out as said radio wave;
a receiving section to which the radio wave received by said receiving antenna section is transmitted as a signal from said receiving antenna section;
beam switching instrument which switches the beam direction sequentially when said receiving antenna section receives said radio wave in said each different beam direction, and which thereby controls a monitoring area; and
a running information storing section for storing running state information of said vehicle, wherein said receiving antenna section includes a first power feed section and a second power feed section, and wherein on the basis of said running state information stored in said running information storing section, said beam switching instrument performs switching such that power is fed to either said first power feed section or said second power feed section.

Abstract
A monitoring apparatus of the present application comprises: a transmission antenna section for sending out a radio wave of single beam having a wide angle or alternatively a radio wave having a narrower (angular) range in a plurality of beam directions; a receiving antenna section for receiving the radio wave in a plurality of beam directions transmitted by the transmission antenna section and then reflected by the target and for having a first power feed section and a second power feed section; a transmission section for transmitting to the transmission antenna section a signal to be sent out as the radio wave; a receiving section to which the radio wave received by the receiving antenna section is transmitted as a signal from the receiving antenna section ; and beam switching instrument which performs a switching operation such that power should be fed to either the first power feed section or the second power feed section, which thereby forms the beam directions of two radio waves, and which thereby controls a monitoring area.

15. A monitoring control method in a vehicle-installed monitoring apparatus of sending out a radio wave, then receiving a radio wave generated by reflection of the radio wave, and thereby detecting a target including a material body and/or a human body, wherein
said method includes the step of determining which monitoring area among a plurality of monitoring areas that can be monitored when a beam direction of the radio wave is switched should be activated at which timing on the basis of running state information of said vehicle, to control the monitoring area.
