An electronic scanning radar apparatus includes a transmission unit configured to transmit a transmission wave, a receiving unit including a plurality of antennas receiving an incoming wave coming from a target, a beat signal generation unit configure to generate beat signals in response to the transmission wave and the incoming wave, a frequency resolution processing unit obtaining complex number data calculated from beat frequencies having signal levels obtained by performing a frequency resolution for the beat signals based on a predetermined frequency width, a peak detector detecting an existence of a present target by detecting peak signal levels of the beat frequencies, a target link unit associating between the present target detected in a present detecting cycle and a past target detected in past detecting cycles; and a direction detecting unit calculating a direction of the incoming wave based on the weighted averaging process. |
