Summary:To accurately and easily determine whether or not a DFS function is applied even under an environment in which various antennas are applied.SOLUTION: A radar detection program outputs a data series of a corrected reception signal level obtained by correcting and converting a signal level of a received radio signal with a receiving antenna gain, stores radar information of a target radar for DFS control and radar threshold level and generates a memory storage periodic signal having a predetermined period using the radar information and a radar mask indicating a signal pattern of a radar pulse corresponding to the radar information using the period, samples the data series of the corrected reception signal level by a period of the memory storage periodic signal and stores the corrected reception signal level in memory as sample data by the period, determines whether or not a radar wave exists by comparing a data series of the sample data read from the memory with a radar mask and comparing with the radar threshold level, and starts the DFS control when detecting the radar wave.SELECTED DRAWING: Figure 1 【課題】 様々なアンテナが適用される環境下においても、DFS機能の適用要否を正確かつ簡易に判定する。【解決手段】 受信した無線信号の信号レベルを受信アンテナゲインで補正換算した補正受信信号レベルのデータ系列を出力する。DFS制御対象レーダのレーダ情報とレーダ閾値レベルを格納し、レーダ情報を用いて所定の周期を有するメモリ格納周期信号と、その周期を用いてレーダ情報に対応するレーダパルスの信号パターンを示すレーダマスクを生成する。補正受信信号レベルのデータ系列をメモリ格納周期信号の周期でサンプリングして、当該周期で補正受信信号レベルをサンプルデータとしてメモリに格納する。メモリから読み出したサンプルデータのデータ系列とレーダマスクとの合致比較、およびレーダ閾値レベルとの比較を行ってレーダ波の存在の有無を判定する。レーダ波の存在を検出したときに、DFS制御を開始する。【選択図】 図1
