Method and system for simulating a radar image

A system for simulating an image of a terrain scanned by a simulated radar beam generated by a simulated radar antenna, comprising:

• a first calculation unit comprising a first processor for calculating a power reflected by the terrain while an orientation of the simulated radar antenna is varied within a scanning antenna range;
• a second calculation unit comprising a plurality of second processors for calculating a convolution power for the terrain while the orientation of the simulated radar antenna is varied within the scanning antenna range, said calculating on a first processor and said calculating on a plurality of second processors being performed concurrently and in parallel;
• an image generating unit for combining the power reflected by the terrain and the convolution power to obtain combined data, generating a radar image using the combined data and outputting the radar image.
