PROBLEM TO BE SOLVED: To reduce the difference between the estimated radiation direction of an electromagnetic wave and the actual radiation direction of an electromagnetic wave.SOLUTION: An electromagnetic wave detection device 10 comprises: an irradiation part 11; a first detection part 17; a traveling part 20; a storage party 13; and a control part 14. The irradiation part 11 irradiates an object ob with an electromagnetic wave. The first detection part 17 detects a reflection wave of the electromagnetic wave with which the object ob is irradiated. The traveling part 20 has a plurality of traveling elements px. The plurality of traveling elements px change the travel of the reflection wave toward the first detection part 17 for each of irradiation positions of the electromagnetic wave with which the object ob is irradiated. The storage part 13 stores information on the radiation direction of the electromagnetic wave. The control part 14 updates the information on the radiation direction on the basis of the positions of the traveling elements px causing the reflection wave to travel toward the first detection part 17 when the first detection part 17 detects the reflection wave.SELECTED DRAWING: Figure 1 【課題】推定される電磁波の放射方向と実際の電磁波の放射方向との差異を低減する。【解決手段】電磁波検出装置１０は照射部１１と第１の検出部１７と進行部２０と記憶部１３と制御部１４とを有する。照射部１１は電磁波を照射する。第１の検出部１７は対象ｏｂに照射された電磁波の反射波を検出する。進行部２０は複数の進行素子ｐｘを有する。複数の進行素子ｐｘは対象ｏｂに照射された電磁波の照射位置別に当前記反射波の第１の検出部１７への進行の可否を切替える。記憶部１３は電磁波の放射方向に関する情報を記憶する。制御部１４は第１の検出部１７が反射波を検出するときに反射波を第１の検出部１７に進行させている進行素子ｐｘの位置に基づいて放射方向に関する情報を更新する。【選択図】図１
