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 storage means in which is stored the distribution of performance records of the relative distance indicated by a radio signal having arrived via a navigation monitoring automatic broadcasting system and the level of the radio signal, and determination means for determining the authenticity or normality of the radio signal as a correlation between the pair of the level of the radio signal having arrived via the navigation monitoring automatic broadcasting system and the relative distance calculated from the radio signal and the distribution.
【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が示す相対距離と、前記無線信号のレベルとの実績の分布が格納された記憶手段と、前記航行監視自動放送システムを介して到来した無線信号のレベルと前記無線信号から算出された相対距離との対と、前記分布との相関として、前記無線信号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
