PROBLEM TO BE SOLVED: To determine the existence or non-existence, or the possibility of existence, of the transmission end of an arrived radio signal with high accuracy without significantly changing a basic configuration from conventional examples pertaining to a radio signal determination device for determining the existence or non-existence, or the possibility of existence, with regard to the transmission end of a radio signal that arrived at an antenna via a navigation monitoring automatic broadcasting system.SOLUTION: The present invention comprises bearing calculation means for calculating the relative bearing of a position indicated by a radio signal having arrived via a navigation monitoring automatic broadcasting system, arrival direction specification means for specifying the arrival direction of the radio signal, and determination means for determining the authenticity or normality of the radio signal or the position as a difference between the bearing and the arrival direction.

    【課題】本発明は、航行監視自動放送システムを介して空中線に到来した無線信号の送信端について存否や存在の可能性を判別する無線信号判別装置に関し、従来例に比べて基本的な構成が大幅に変更されることなく、到来した無線信号の送信端の存否やその可能性を確度高く判別できることを目的とする。【解決手段】航行監視自動放送システムを介して到来した無線信号で示される位置の相対的な方位を求める方位算出手段と、前記無線信号の到来方向を特定する到来方向特定手段と、前記方位と前記到来方向と差として、前記無線信号または前記位置の真偽または正規性を判別する判別手段とを備える。【選択図】図1
