An on-board radar apparatus includes a transmission wave generating unit configured to generate a first modulated wave, a second modulated wave, and a third modulated wave which are different from each other, a transmitting antenna configured to transmit a transmission wave based on the first modulated wave, the second modulated wave, and the third modulated wave, a receiving antenna unit configured to receive a reception wave arriving by allowing the transmission wave to be reflected by an object, and an azimuth detecting unit configured to detect a signal based on the first modulated wave, the second modulated wave, and the third modulated wave from the reception, wave and to detect an azimuth of the object based on the detected signal.

On-board radar apparatus, object detection method, and object detection program

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.
