PROBLEM TO BE SOLVED: To provide a navigation information discrimination apparatus which assesses authenticity of transmission information transmitted by radio via a navigation monitoring automatic broadcasting system, or authenticity of a transmitting end of the transmission information, and which provides highly accurate assessment of authenticity of radio stations and transmission information without sacrificing compatibility with original specifications and configurations.SOLUTION: A navigation information discrimination apparatus includes: first position acquisition means which acquires a first position of a target detected by a radar and being a subject for tracking by the radar; second position acquisition means which acquires a second position of the target transmitted by radio via a navigation monitoring automatic broadcasting system; and discrimination means which identifies an actual coverage area of the radar and assesses authenticity of a radio station or transmission information from a correlation between the first position and the second position in a range of the coverage area.
【課題】本発明は、航行監視自動放送システムを介して無線伝送された伝送情報、またはその伝送情報の送信端の真偽を判別する航行情報判別装置に関し、本来的な仕様および構成に対する適合性が損なわれることなく、無線局や伝送情報の真偽の判別が確度高く達成されることを目的とする。【解決手段】 レーダによって探知され、または前記レーダに連係する追尾の対象となっている目標の第一の位置を取得する第一の位置取得手段と、前記目標について航行監視自動放送システムを介して無線伝送された第二の位置を取得する第二の位置取得手段と、前記レーダの実体的な覆域を識別し、前記覆域の範囲における前記第一の位置と前記第二の位置との相関として、前記無線局または前記伝送情報の真偽を判別する判別手段とを備える。【選択図】図1
