Abstract
Provided is a radar device that may perform an angle estimation of an incoming direction of an incoming wave with high accuracy because of increased angular resolution and has an increased dynamic range. In a transmission antenna Tx, transmission antenna elements Tx, Tx, Tx, and the like of number m of three or more are arranged in a straight line at equal intervals of wavelength λ of a transmission wave. In a reception antenna Rx, reception antenna elements Rx, Rx, and the like, are arranged in a straight line at equal intervals. Circuitry generates virtual reception antenna elements Rxa, Rxb, . . . , and Rxq between the respective reception antenna elements by adjusting a phase of a reception signal to control the directivity of a radio wave to perform beam-forming between transmission antenna elements in each pair.
