About Doppler Weather Radar
What is Radar?
Radar (Radio Detection and Ranging) 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.
What is Doppler Principle?
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.
What is Doppler Radar?
Doppler radar is a specific radar that uses the Doppler principle to produce relative motion data about objects at a distance.
Indian Doppler Radar:
Also known as INDRA series of 2D Radars and developed by DRDO for the use of Airforce and the Army. Some have been even exported to Sri Lanka.
INDRA-1: Is low-level target detection mobile surveillance radar.
INDRA 2: Is a modified version of INDRA radar for ground controlled interception of targets. It uses pulse compression to detect low flying aircraft.
Application of Doppler Radars:
