| 摘 要： | A modulated microwave reflectometry has been successfully developed on HL-2A, which can be used to measure the plasma density profile with time-delay method. This microwave reflectometry has two frequency ranges （26.5 to 40 GHz and 40 to 60 GHz） and it is suitable for measuring the plasma density ranging from 0.8×10^13 cm^-3 to 4.5×10^13 cm^-3. The temporal resolution is i ms and the spatial resolution is about 1 cm. This paper will present the basic principle of the microwave reflectometry, parameters calibration of the equipment and the experimental results on HL-2A tokamak.
