Abstract:
1. An electronic scanning radar apparatus mounted on a moving object, comprising: a receiving unit including a plurality of antennas receiving a received wave arriving from a target having reflected a transmitted wave; a beat signal generating unit configured to generate a beat signal from the transmitted wave and the received wave; a frequency resolving unit configured to resolve the beat signal in beat frequencies having a predetermined frequency bandwidth and to calculate complex data based on the beat signal resolved for each beat frequency; and an azimuth detecting unit configured to calculate a direction of arrival of the received wave based on original complex data which is the complex data calculated based on the beat signal, wherein the azimuth detecting unit includes a data extending unit configured to generate extended complex data by extending the number of data based on the original complex data, and a first computation processing unit configured to calculate the direction of arrival of the received wave based on the extended complex data.
