Abstract : This paper provides a notion about weather station accomplished of receiving and processing satellite signal, in order to produce an image to assist in observing weather conditions. To achieve this, a Quadrifilar Helix antenna (QFH), a receiver and a PC sound card is used in the hardware part. The output from the sound card is recorded as a wave file. This wave file is decoded using processing techniques in various software environments. This paper provides a comprehensive report on antenna construction procedures and signal processing techniques used to achieve a complete readable weather image. Also using these decoded images, how far application oriented information can be retrieved is analysed.
