MEASUREMENT DEVICE

To suitably achieve the oscillation and reception of an electromagnetic wave with a single element.SOLUTION: A measurement device (10) comprises: a transmission/reception unit (150) for performing an irradiation operation for irradiating an object (200) with an electromagnetic wave and a reception operation for receiving the electromagnetic wave reflected by the object; a detection unit (160) for detecting electromagnetic wave information received by the transmission/reception unit; a control unit (110) for making the transmission/reception unit perform one of the irradiation operation and the reception operation; and an output unit (120) for outputting a signal for making the transmission/reception unit radiate an electromagnetic wave when the control unit makes the transmission/reception unit to perform the irradiation operation, and outputting a signal inputted to the detection unit from the transmission/reception unit when the control unit makes the transmission/reception unit to perform the reception operation.SELECTED DRAWING: Figure 1 【課題】１つの素子で電磁波の発振及び受信を好適に行う。【解決手段】測定装置（１０）は、電磁波を対象物（２００）に照射する照射動作、及び対象物にて反射された電磁波を受信する受信動作を行う送受信部（１５０）と、送受信部で受信された電磁波の情報を検出する検出部（１６０）と、送受信部に照射動作及び受信動作のいずれかを行わせる制御部（１１０）と、制御部が照射動作を行わせている場合に、送受信部側に電磁波を照射させるための信号を出力し、制御部が受信動作を行わせている場合に、検出部側に送受信部側から入力された信号を出力する出力部（１２０）とを備える。【選択図】図１
