Starting from digital elevation model (DEM), I and Q raw data are generate. In the paper we present the algorithm our simulator is based on, its performance and some examples of raw and compressed data.conference paper54dcce078580fe1368eeae23https://earth.esa.int/documents/10174/1589798/ESA03.pdf54dcce078580fe1368eeae23
