Patent ID: 8446312

Claim:
An electronic scanning type radar device mounted on a moving body comprising: a transmission unit transmitting a transmission wave; a reception unit comprising a plurality of antennas receiving a reflection wave of the transmission wave from a target; a beat signal generation unit generating a beat signal from the transmission wave and the reflection wave; a frequency resolution processing unit frequency resolving the beat signal into a beat frequency of a predetermined resolution number and computing a complex number data; a target detection unit detecting a peak value from an intensity value of the beat frequency and detecting an existence of the target; a correlation matrix computation unit computing a correlation matrix from each of a complex number data of a detected beat frequency for which the target was detected for each of the antennas; a target consolidation processing unit linking the target in a present detection cycle and a past detection cycle based on a distance and a relative velocity; a correlation matrix filtering unit generating an averaged correlation matrix by weighted averaging a correlation matrix of a target in the present detection cycle and a correlation matrix of a related target in the past detection cycle; and a direction detection unit computing an arrival direction of the reflection wave based on the averaged correlation matrix.
