Patent ID: 8102309

Claim:
A radar device, comprising: transmitting means for transmitting a transmitting signal having a plurality of modulation periods; receiving means for receiving a plurality of reflection signals resulting from reflection of the transmitting signal by a plurality of targets; mixing means for mixing the transmitting signal with each of the plurality of received reflection signals received by the receiving means to obtain a plurality of beat signals; frequency analyzing means for analyzing frequencies of each of the plurality of beat signals; and a target detection unit that calculates a direction of a target based on a summed correlation matrix in which correlation matrices generated from peak frequency spectra having peak frequencies according to a plurality of frequency analyzing results obtained by the analyzing of the frequency analyzing means in the plurality of modulation periods that do not satisfy a given condition are summed together, wherein the target detection unit includes a correlation matrix addition prohibition unit that prohibits addition of a correlation matrix generated from a peak frequency spectrum having a peak frequency that satisfies the given condition, when a peak frequency in the plurality of modulation periods satisfies the given condition.
