Read about how radar images of weather fronts are developed on the National Weather Service web site [1]. The basics are as follows (from NWS):
What are the different types of radar images?
There are six different types of images currently available for the RIDGE radar display: Base Reflectivity, Composite Reflectivity, Base Velocity, Storm Relative Motion, One-hour Precipitation and Storm Total Precipitation.
The base reflectivity image is from the lowest "tilt" angle (0.5°). This means the radar's antenna is tilted 0.5° above the horizon. Learn more about Base Reflectivity. [2]
