  • Patent number: 7605745
    Abstract: 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.

  • Patent number: 7450056
    Abstract: 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.

  • Patent number: 7233279
    Abstract: In order to provide the method and the device for distance measurement by pulse radar that securely eliminates the false echo from the distance over the detectable limit determined by the pulse generation cycle, the pulse radar comprises the pulse signal sending unit that generates the pulse signals with different cycles at OSC 9a˜9c, switches to the predetermined intervals by OSC switch 10, and sends the pulse signal to targets, the reflected signal receiving unit that receives the reflected signals and stores the data in the RAM 25, the reflected signal data acquisition unit that obtains the data of each reflected signal, and the reflected signal identification unit that compares the intensity of the reflected signals obtained at the same lag time point during a certain time period after sending the pulse signal for reference and identifies the reflected signals of the sent pulse signal for reference.

  • Patent number: 7095363
    Abstract: 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.

  • Patent number: 7006033
    Abstract: An embodiment comprises a unit generating a control pulse signal by delaying a basic signal in generating a transmission pulse, and a unit performing a gate operation on a received signal using the control pulse signal. Another embodiment comprises a unit generating a control pulse signal by delaying a signal generated using a first basic signal, a second signal for phase modulation having a lower frequency than the first signal, and a pseudo-random signal generated at an intermediate frequency between the frequencies of the first and second signals, and a unit performing the gate operation.
