摘要：
Ka-Band scanning frequency microwave Reflectometer is designed and developed to measure the plasma density profile in steady state plasma. It scans the full band (24-36 GHz) in 10 mu s. It measures the density profile from minor radius r = 14 to 17.34 cm in SST-1 plasma. Single antenna and optics is used for transmitting and receiving purpose. Quadrature phase detector is used for absolute phase determination. 40m long oversized waveguide of X-Band and Mitre Bends are used to reduce the losses in plasma path. The design and working of Reflectometer are discussed in this paper.
