Cloud Radar: Predicting The Weather More Accurately

| Quote From Source: | The radar consists of a millimetre-wave frequency source that continuously emits a low power signal in the vertical direction that is frequency modulated. A signal is returned, mainly due to what is known as ‘back-scattering' from water droplets and ice crystals in the atmosphere. This signal is picked up by a receiver and converted to a microwave signal, which is then digitised, analysed and a real-time image of the returned signal intensity versus altitude is displayed for the user.
