Lecturer Dr. Husham Jawad Ahmad at the Department of Communication Engineering gave a seminar entitled “Basic Principles of Weather Radar” on 26th Nov 2021 at 12:00 PM. The seminar focused on a weather radar which is an instrument used to locate precipitation, calculate its motion, intensity, and determine the type (rain, snow, hail, etc.). A weather radar sends out a pulse of electromagnetic energy into the atmosphere. If that piece of energy interacts with something in the environment, it will reflect energy back to the weather radar and we can sense it. Today most radars use the Doppler effect and have dual-polarization. A Doppler radar determines whether movement is toward or away from the radar. Dual-polarization is a combination of radar design and software algorithms that help identify the type of precipitation.
