Abstract :
Millimeter wave radar has a unique advantage on detecting cloud microphysical structure. However, it is easy to cause the velocity aliasing due to its short wavelength. Velocity dealiasing is an effective means of detecting wind field information with Doppler radar. This paper reviews the cause of velocity folding and proposed a human-machine interaction method aimed at millimeter wave radar in the RHI scanning. It is concluded that the algorithm is very efficient and can produce high quality velocity data.
