Abstract
Discharge measurement during flood season is very difficult. Microwave water surface current meter (MWSCM) can measures river surface velocities easily without contacting water. This study introduces its improved version, MWSCM for general use. The existing version of MWSCM is for floods so that its applicable period in a year is short. It has been improved to extend its applicability in a year. The range of measurable velocity for MWSCM for general use is extended so it can be applied during normal flows as well as high flows. MWSCM for general use can measure the velocity range of $0.03{\sim}20.0ms^{-1}$, whereas MWSCM for floods can measure the velocity range of $0.5{\sim}10.0ms^{-1}$. To make such innovation of MWSCM for general use, the applied microwave frequency of MWSCM was changed from 10 GHz to 24 GHz. Waveguide slot array antenna has been designed with the new development of the circuit of transmitting and receiving part. Improvement requests on the existing MWSCM for floods - weight lightening, measured velocity stabilization, self-test, low power consumption, and waterproof and dampproof - from the users of it have been reflected for the development of the new version of MWSCM.
