RHI scan mode is widely used in weather modification field because it can provide more detailed vertical structures of cloud and rain echoes. The traditional RHI mode needs so many manual operations to select its crosssection orientations one by one, and the information obtained is very limited. Therefore, CINRAD automatic detection functions are limited by these disadvantages. The developed algorithm introduces how the combined RHI products are autoimplemented based on current volume scan mode, to enhance the CINRAD operational functions.
