摘要： There is provided a radar device which detects targets by performing a signal processing procedure based on a frequency-modulated continuous wave and the reflected waves of the transmission wave from the targets. A signal processing unit is configured to periodically perform the signal processing procedure based on beat signals which are differential waves between the transmission wave and the reflected waves. A monitoring unit is configured to monitor each of processing states of processes which are sequentially performed in the signal processing procedure. A changing unit is configured to change a processing condition for the subsequent-stage processes of a process, according to the processing state of the process, if the monitoring unit detects that the process is in a high load state, from the processing states.

摘要： There is provided a radar device for detecting a target based on a frequency-modulated transmission wave and reflected waves of the transmission wave from the target. An extracting unit configured to extract peaks corresponding to the target based on beat signals which are differential waves between the transmission wave and the reflected waves. A generating unit configured to generate instantaneous values corresponding to the peaks based on the peaks extracted by the extracting unit. A filtering unit configured to generate a target data item corresponding to the instantaneous values by performing chronological filtering on the instantaneous values generated by the generating unit. The filtering unit can assign a plurality of instantaneous values to an assignment range corresponding to one target data item, based on individual elements included in the instantaneous values.
