To expand a detection range of a radar system by synchronizing multiple sensors operating individually with a simple configuration.SOLUTION: A radar system for measuring a moving body by using a first Doppler sensor and a second Doppler sensor operating individually includes: a control part for controlling temporary stop and restart of output of a transmission signal in one of the first Doppler sensor and the second Doppler sensor; a reception circuit for detecting a reception signal by each of the first Doppler sensor and the second Doppler sensor; and a synchronization determination part for determining predetermined timing appearing in a detection result of the reception signal in response to a change in the transmission signal as synchronization timing.SELECTED DRAWING: Figure 4 【課題】簡単な構成で個別に動作する複数のセンサを同期させてレーダーシステムの検知範囲を拡張する。【解決手段】個別に動作する第１のドップラーセンサと第２のドップラーセンサを用いて移動体を計測するレーダーシステムにおいて、前記第１のドップラーセンサと前記第２のドップラーセンサのいずれか一方における送信信号の出力の一時停止と再開を制御する制御部と、前記第１のドップラーセンサと、前記第２のドップラーセンサのそれぞれで、受信信号を検波する受信回路と、前記送信信号の出力の変化に対応して前記受信信号の検波結果に現れる所定のタイミングを同期タイミングと判定する同期判定部と、を有する。【選択図】図４
