Patent number: 7605745Abstract: Provide an on-vehicle radar device that performs transmission control of a monitoring signal, following fixed rules, so that interference with other radar devices can be avoided with certainty. An on-vehicle radar device comprises a transceiver which transmits/receives a monitoring signal at a specified frequency band and transmits a priority order signal at a frequency within the above-mentioned frequency band, and a controller which switches the signals transmitted by the transceiver. The transceiver receives a priority order signal of another radar device, and when interference with the signal of the other radar device is detected, the controller, based on the priority order of that other device and on the priority order of the device itself, shifts, by a specified frequency amount, the frequency band of the monitoring signal transmitted by the transceiver.Type: GrantFiled: March 30, 2007Date of Patent: October 20, 2009Assignees: Fujitsu Ten Limited, Fujitsu LimitedInventors: Kanako Honda, Osamu Isaji, Kazuo Shirakawa, Naofumi Ohkubo, Tetsuo Seki

Patent number: 7450056Abstract: The search/detection apparatus modulates a carrier signal by a modulation signal, generates a probe signal for detecting the location of a target, and receives the probe signal reflected by the target as an echo signal. Then, the search/detection apparatus detects the existence of an interference signal other than the echo signal from the received signal and modifies the parameter of the modulation signal and/or carrier signal.Type: GrantFiled: May 31, 2006Date of Patent: November 11, 2008Assignees: Fujitsu Limited, Fujitsu Ten LimitedInventors: Kazuo Shirakawa, Naofumi Ohkubo, Tetsuo Seki, Kanako Honda, Osamu Isaji

Patent number: 7095363Abstract: A pulse radar apparatus uses different frequencies, for example, frequencies one of which is a multiple or a submultiple of the other for a signal which becomes a reference of a control pulse for controlling a gate operation for a reception signal and a signal which becomes a base of generation of a transmission pulse. As a result, even if noise is caused by the gate operation, its influence can be removed in the processing of reception signals having different frequencies.Type: GrantFiled: March 26, 2004Date of Patent: August 22, 2006Assignee: Fujitsu LimitedInventors: Satoshi Ishii, Yoshikazu Dooi, Hiroyuki Yatsuka, Tetsuo Seki
