PROBLEM TO BE SOLVED: To minimize the probability of the occurrence of radio wave interference with a device of the same or similar type arranged in the vicinity of a radio sensing device without increasing a cost and an occupied bandwidth.SOLUTION: There is provided a radio sensing device having N antennas (N is a natural number of 1 or more), and a switching control part that sequentially switches the antennas and performs radio wave scanning to a part of or all directions in a circumferential shape or a spherical shell shape, and including a random number generation part that generates random numbers, where the switching control part performs an operation to switch the antennas within a time M times (M is a positive integer) a unit time required for sequentially scanning through all the N antennas on the basis of a random number generated as the order to select the N antennas.SELECTED DRAWING: Figure 4
【課題】近隣に配置された同種あるいは類似の装置との間で電波干渉が起きる確率を、コストや占有帯域幅を増やすことなく最小化する。【解決手段】Nを1以上の自然数とするN本のアンテナと、アンテナを順次切り替え、円周状または球殻状で、その一部あるいは全部の方位に対して電波走査を行う切替制御部を有する無線センシング装置において、乱数を生成する乱数生成部を備え、切替制御部は、N本のアンテナ全部を一通り順次走査するために要する単位時間のM(M;正の整数)倍の時間内において、N本のアンテナの選択の順番を生成した乱数に基づいて、切り換える操作を行なう。【選択図】図4
