Simulation Study of Precipitation Using Bistatic Spaceborne SAR Architecture.

The technology of Synthetic Aperture Radars (SAR) is growing at a rapid pace in the last decade. The advancements in SAR opens doors to explore more scientific problems which were considered impactical in the past. The study of meteorological targets using spaceborne SAR platforms is an emerging field of study. In the past, spaceborne monostatic SAR for observing precipitation echoes was studied. In this paper, a bistatic architecture of the SAR system is considered for studying the precipitation target using signal simulations. The precipitation radar parameters on-board the GPM core satellite is considered for the simulation study. The architecture of the bistatic SAR considered is introduced and the various factors considered for a bistatic SAR is studied in detail. This simulation work currently being researched on shows the initial results. The results presented will aid in understanding the precipitation echoes observed from spaceborne SAR platforms.
