<p><P>PROBLEM TO BE SOLVED: To resolve a problem wherein the convetional transmission and reception integrated antenna system radar can not receive reflection wave from obstacles during a period of emitting transmission signal in the air, although there is a method surely executing the detecting a target by changing a transmission and reception switching frequency by time sharing, while obtaining high reception level from a target in a short distance to a target in a long distance. <P>SOLUTION: The transmission and reception integrated antenna system radar of the present invention obtains information on an object around by receiving reflection wave of high frequency signal transmitted by itself and processing, and comprises: an antenna for transmission and reception for transmitting and receiving high frequency signal of a specific frequency; an electromagnetic wave detecting means for detecting the high frequency signal transmitted by the transmission and reception antenna and the reflection wave of the high frequency signal from objects; and a detection circuit detecting whether the electromagnetic wave detected with the electromagnetic wave detecting means is the high frequency signal transmitted from the antenna, or the reflection wave of the high frequency signal from the objects. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
