Visor's SAR data simulator is perfect for testing and debugging new image processing algorithms. The simulator provides high precision data for radar frequencies from P-band to Ka-band and above.  It is optimized to support hundreds of millions of point targets over areas of hundreds of thousands of square kilometers, making it suitable for testing fidelity and throughput of imaging algorithms.  It also supports moving targets for GMTI algorithm testing.
