PROBLEM TO BE SOLVED: To make possible highly accurate radar observation.SOLUTION: A beam information generation device as one embodiment of the present invention includes a distance calculation unit and a beam angle calculation unit. The distance calculation unit calculates the distance from a receiver to a transmission beam in accordance with the beam direction of each of a plurality of reception beams formed by the receiver toward the transmission beam. The beam angle calculation unit calculates, on the basis of the distance calculated by the distance calculation unit, the beam angle of the reception beam so that variations in the size of each reception beam are suppressed in the transmission beam. 【課題】精度の高いレーダ観測を可能にする。【解決手段】本発明の一態様としてのビーム情報生成装置は、距離計算部と、ビーム角計算部とを備える。前記距離計算部は、送信ビームに向けて受信機により形成する複数の受信ビームの各々のビーム方向に応じて、前記受信機から送信ビームまでの距離を、送信ビーム情報に基づき計算する。前記ビーム角計算部は、前記距離計算部により計算される距離に基づき、前記送信ビーム内において各受信ビームのサイズのばらつきが抑制されるように、前記受信ビームのビーム角を計算する。【選択図】図１
