JRM Technologies specializes in advanced sensor phenomenology modeling and simulation. The firm is focused on bringing better predictive physics and sensor phenomenology to all areas of military simulation -- particularly in the area of real-time training simulators. The firm now offers state-of-the-art spectral signature synthesis and atmospheric propagation modeling for a broad range of sensor simulation applications, including non-real-time, near-real-time, real-time, virtual, constructive, multi-spectral, hyper-spectral, radar and communications. When linked into Image Generators (IGs) with straightforward graphics-rendering interfaces, the company's SigSim technology enables credible real-time dynamic predictive signature and atmospheric capabilities.
