Radio frequency (RF) waves are useful tools for heating plasma and for driving a current in plasma. In order to understand RF wave heating and to develop an efficient heating scenario, a qualitative internal RF field measurement should be established. Microwave reflectometry is one such measurement, and it measures electron density fluctuations induced by RF electric fields. An O-mode microwave reflectometer with a probing frequency of 30.5 GHz has been designed and installed on LHD to measure
