<p><P>PROBLEM TO BE SOLVED: To realize a vehicle-mounted radio wave radar system capable of preventing noise which is radiated from a pin, from propagating over the whole circuit board in a storage case, while suppressing rise of its cost. <P>SOLUTION: The vehicle-mounted radio wave radar 1, which is attached to a vehicle, radiates a radar beam, receives the radar beam reflected by an object to be detected and detects a distance and a relative velocity between the vehicle and the object to be detected, comprises: a conductive case 2; a signal processing circuit board 3 disposed in the case 2; a connector 5 which has a pin 5a connected to the signal processing circuit board 3 and can be connected electrically to an external device disposed outside the case 2; and a conductive partition plate 7, which is disposed in the storage case 2, contacts a ground plane 6 of the signal processing circuit board 3 and includes the connector 5 in cooperation with the storage case 2. The storage case 2 and the partition plate 7 prevent the noise which is radiated in a space from the pin 5a from emitting out of a connecter included space 2a. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
