Abstract
In an electronic scanning radar apparatus, a receiving unit includes a plurality of antennas receiving a reflected wave arriving from a target having reflected a transmitted wave as a received wave. A beat signal generating unit generates beat signals from the transmitted wave and the received wave. A frequency resolving unit resolves the beat signals in beat frequencies having a predetermined frequency bandwidth and calculates complex data based on the resolved beat signals for each beat frequency. An azimuth calculating unit estimates an order of a normal equation used to calculate a DOA of the received wave on the basis of eigenvalues of a primary order matrix having complex data calculated from the beat signals as elements, creates a secondary order normal equation based on the estimated order, and calculates the DOA of the received wave based on the created secondary order normal equation.
