  • Patent number: 9459342
    Abstract: A radar device capable of reducing load of a clustering process and improving the tracking performance is provided. A tracking calculation unit 116 of a radar device 100 performs a clustering process, in which an input detected data set is grouped into clusters, and a tracking process, in which an averaged value and a prediction value are calculated for each of the clusters. In the radar device 100, the shape of cluster areas for grouping the detected data is defined to be a fan shape. The clustering process and tracking process using fan-shaped cluster areas can reduce the load of the clustering process and improve the tracking performance.

  • Patent number: 8897396
    Abstract: Provided is a pulse receiver capable of receiving a burst signal and decoding the burst signal with a bit error rate reduced to a target value or less by controlling a determination threshold such that decoding success rate is equal to or less than a predetermined value. A decode unit 140 decodes a pulse train 20 to information 30, counts the number of decoding successes for a predetermined time period and outputs the counted number (decoding success rate DR) to a control unit 150. The control unit 150 uses as a basis the decoding success rate DR communicated from the decode unit 140 to control the set value of reference voltage Vth used in the comparator 130.
