Abstract :
MST Radars operated at VHF and UHF frequencies operate on the principle that radio waves in these frequency bands are scattered and/or reflected by fluctuations in the radio refractive index of the atmosphere. The paper is mainly concerned with reflection echoes obtained from the vertical direction in the troposphere. The parameters Wx and Wy are found to be highly correlated. The M profile agrees well upto 7 km with the vertical echopower profile
