This band is also shared with some police speed radars and some space radars.University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction.Most major airplanes are equipped with an X band radar to pick up turbulence and other weather phenomena.

Due to the small size of the radar, it can therefore be portable like the Doppler on Wheels (DOW).

X band radars also attenuate (become less effective) very easily, so they are used for only very short range weather observation.

These radars are used for studies on cloud development because they can detect the tiny water particles and also used to detect light precipitation such as snow.

Because of the smaller wavelength, the X band radar is more sensitive and can detect smaller particles. X band radars: They operate on a wavelength of 2.5-4 cm and a frequency of 8-12 GHz. Types Of Doppler Radars : Doppler radar can be divided into several different categories according to the wavelength which are L,S,C,X,K.

DWR has the equipment to measure rainfall intensity, wind shear and velocity and locate a storm centre and the direction of a tornado or gust front.

Based on Doppler principle the radar is designed to improve precision in long-range weather forecasting and surveillance using a parabolic dish antenna and a foam sandwich spherical dome.

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

This variation gives direct and highly accurate measurements of the radial component of a target’s velocity relative to the radar.

It does this by bouncing a microwave signal off a desired target and analysing how the object’s motion has altered the frequency of the returned signal.If they are moving closer frequency increases and vice versa.

When the source and the signal are in relative motion to each other there is a change in the frequency observed by the observer.It 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. Timely weather forecasts and warnings would ensure the governments make advance plans and initiate rescue measures. Uttarakhand and Himachal Pradesh are highly prone to cloud bursts, landslides, heavy rain and snowfall.Covering the central and western Himalayas, these dual polarised radars will gather atmospheric variations and pick signals of extreme weather events.This new system will capture, process and make available for use satellite data within seven minutes as opposed to 20 minutes taken by earlier systems.A multi-mission meteorological data receiving and processing system developed in collaboration with Indian Space Research Organisation (ISRO) was also launched.The DWR has been designed and developed by ISRO and manufactured by Bharat Electronics Limited (BEL), Bengaluru. Recently, Ministry of Earth Sciences commissioned two indigenously built X-Band Doppler Weather Radars (DWR) which will closely monitor the weather changes over the Himalayas.
