Figure 1. Sample of SAR product (Greenland)
In contrast to a hardware system the software based processor uses off-the-
shelf computers for the generation of the products. The planned configura-
tion is depicted in Figure 2. From a software point of view the basic dif-
ference to a hardware processor lies in the fact that a high-level-language
compiler goes along with each CPU. Therefore, this type of processor is more
flexible, it can be adapted to new requirements and the software is portable
to the latest hardware. With the emerge of even faster array processors like
the 10 Gigaflops ETA 10 real time processing can be achieved.
