Doppler Radar

🔹 About

1. A Radar is a device which uses electromagnetic waves in the microwaves region to detect location (range & direction), altitude, intensity and movement of moving and non-moving objects.

2. A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance

🔹 Doppler effect: When the source and the signal are in relative motion to each other there is a change in the frequency observed by the observer. If they are moving closer frequency increases and vice versa.

🔹 Doppler Weather Rada

1. The radar is designed to improve precision in long-range weather forecasting and surveillance using a parabolic dish antenna and a foam sandwich spherical radome.

2. It is to measure rainfall intensity, wind shear and velocity and locate a storm centre and the direction of a tornado or gust front.

🔹 Application

1. To study cloud development

2. Can be used for short range weather observation

3. Aero Navigation

4. Support Police work
