Synthetic Aperture Radar (SAR) provides high resolution ground images independently of weather or time of day conditions. In military scenarios, jamming transmitters are used to neutralize SAR as a source of strategic information. These jamming transmitters are designed to cause jamming signals in the receiver of the radar which separate themselves from the true reflected echo signals by means of modulation in amplitude, phase or frequency. The area of disguise, i.e. the area covered by the jamming transmitters, and its different levels of jamming power depend upon many various parameters and geometric conditions specific for the SAR-system and jamming transmitters in question. Since simulation is a cost and time efficient way of getting a reality perception about a future jamming scenario it is desirable to develop a simulation program that according to input data generates an estimated area of disguise, bound to geographic points, where the jamming overweight is visualiized with a suitable scaling. This makes it possible to extract suitable locations for the jamming transmitters from simulations when a certain area of interest needs protection. In this report such a program is described.
