Weather Doppler Radar Processing

Weather prediction and  estimation is a study that has proven to be very useful for human beings. Be it  a travel plan or launching a space craft, to know in advance the possible turns  the weather could take has become very important. Sankya’s Doppler Weather  Radar Image Processing Software does all this and more. It is an image processing  software to process Doppler weather radar data to estimate and show as  accurately as possible the atmospheric parameters for weather prediction and  rainfall estimation. The results are charted and presented in graphical form that  is familiar to meteorologists. IDL and JAVA are the tools used to develop this  software.

A Doppler  radar is one that makes use of the Doppler effect in order to come  up with velocity information  about objects at a distance. This is carried out by beaming a microwave signal towards a preferred target  and then listening for its reflection. After this an analysis is carried out on  how the frequency of the signal that returns has been changed by the object's  motion. This slight change in figures gives one very precise and direct  measurements of the radial factors of a target's speed  in relation to the radar. Doppler radars are used in aviation, sounding satellites,  weather forecast and much more.

The weather surveillance radar or the  weather radar is used to identify the precipitation, to calculate the motion,  estimate the type of precipitation and to forecast the intensity and future  happenings of it. Sankya uses a software that functions on pulse-Doppler radar  which has the capacity to detect the droplets of rain and its motion besides  the intensity of the precipitation.  This  can be used to determine storms and other potentially severe weather conditions  and avoid damages.

Sankya’s software uses weather radar  and makes it send pulses in certain direction. These are of microwave radiation  and use a cavity magnetron or klystron tube which is in turn connected to an  antenna. Part of the energy from these pulses will be found bouncing off the  ice particles and droplets that it detects back to the radar station, thereby  determining its size and intensity. As the radar pulses spread out as they  travel away from the radar station, the area of air of the given pulse is  larger for areas far away from the station than those nearby.

Using these effects the software can  effectively use the Doppler Effect to determine the weather parameters. In  weather studies, this becomes a very significant software to hand hold and own.  Most of such software of high sophistication turns out to be very expensive in  purchase and maintenance. But Sankya assures companies not just of products of  the highest of value but also products that are easy to maintain. The service  provided for these products by Sankya is unmatched in terms of professionalism  and quality.
