To provide a secondary monitoring radar system capable of preventing information from being missed.SOLUTION: A secondary monitoring radar system comprises a plurality of secondary monitoring radar devices SSR1-7 of which the cover areas are overlapped with each other, and a communication medium forming a communication link between the plurality of secondary monitoring radar devices. Each of the plurality of secondary monitoring radar devices includes an acquisition unit and a question management unit 40. The acquisition unit receives moving state information relating to an aircraft subjected to monitoring from an adjacent secondary monitoring radar device. In the case where the moving state information cannot be received, the question management unit acquires the moving state information by transmitting a question signal toward the cover area under its own management.SELECTED DRAWING: Figure 3

    【課題】情報の欠落を防止することができる、二次監視レーダシステムを提供する。【解決手段】二次監視レーダシステムは、互いに覆域の重なり合う複数の二次監視レーダ装置SSR1〜7と、複数の二次監視レーダ装置の間に通信リンクを形成する通信媒体とを具備する。そして、複数の二次監視レーダ装置は、取得部と、質問管理部40とを具備する。取得部は、隣接する二次監視レーダ装置から、監視対象の航空機に係わる動態情報を受信する。質問管理部は、動態情報を受信できない場合に、自らの配下の覆域に向け質問信号を送信して動態情報を取得する。【選択図】図3
