Zusammenfassung:To efficiently specify information on the radar signal and position, etc. of a secondary radar.SOLUTION: A method for intercepting secondary radars 1 and 2 comprises: acquiring two or more receiving signals B11-B13 obtained by receiving a peripheral signal including one or more radar signals A1 and A2 sent from the one or more secondary radars 1 and 2 by two or more receivers 11-13, respectively; and specifying first to third pulses P1-P3 of the radar signals A1 and A2 included in each of the input signals B11-B13 on the basis of a relationship between the input signals B11 and B13, or specifying positions of the secondary radars 1 and 2. An interception program performs each step of the interception method in a computer 20, and a recording medium can read the computer recording the interception program.SELECTED DRAWING: Figure 12 【課題】二次レーダーのレーダー信号、位置等の情報を効率的に特定する。【解決手段】本発明の二次レーダー1,2の傍受方法においては、1つ又は複数の二次レーダー1,2から発信される1つ又は複数のレーダー信号A1,A2を含んだ周辺信号を2つ以上の受信装置11~13にてそれぞれ受信した2つ以上の受信信号B11~B13を取得し、これら受信信号B11~B13間の関係に基づいて、各受信信号B11~B13に含まれるレーダー信号A1,A2の第1~第3パルスP1~P3を特定するか、又は二次レーダー1,2の位置を特定する。本発明はまた、当該傍受方法の各工程をコンピュータ20に実行させる傍受プログラムに関し、さらに、発明は、当該傍受プログラムを記録したコンピュータ読み取り可能な記録媒体に関する。【選択図】図12
