ISL provides a wide range of simulation and modeling services for analyzing RF sensors including radar and ELINT. ISL’s expertise and modeling tools are used to provide our customers with a cost-effective means of predicting real-world system performance without the need for costly hardware prototyping and data collection campaigns.
ISL’s tools accurately model the effects of site-specific terrain, land cover, background/civilian targets, sensor-platform interactions and errors in the receive chain, and sensor motion (flexing, vibration, etc.). Thus, they are capable of providing the rigorous physics-based characterization of all the real-world effects that must be considered when designing and testing sensor signal processing algorithms.
RFView is an advanced cloud-based site-specific radio frequency simulation and analysis environment. The simulation environment is built on ISL’s industry-leading Splatter, Clutter, and Target Signal (SCATS) RF phenomenology engine. SCATS has successfully supported numerous advanced development projects for DARPA, Army, Navy, Air Force and other classified customers since 1989. It was one of the earliest site-specific radio frequency (RF) phenomenology analysis tools to provide an accurate characterization of complex RF environments. Uses of the model include system analysis, test planning, high-fidelity synthetic data generation, and signal processing algorithm development. The model provides characterization of target returns, direct path signal, ground scattered signal (clutter for radar), direct path signals from interferers, and ground scattered interference signals (hot clutter, splatter, or terrain-scattered interference).

Under the Knowledge-Aided Sensor Signal Processing and Expert Reasoning (KASSPER) program ISL used the SCATS model to deliver high-fidelity simulated radar data sets to support the needs of our DARPA/AFRL customer. The data sets were used by government and industry organizations to develop and validate advanced adaptive processing algorithms that improve GMTI radar performance in stressing environments. Numerous non-ISL open literature papers have reported results using these data sets.
Designing RF systems for military operations in urban terrain (MOUT) requires site-specific models of built-up areas. ISL has used the Wireless Insite REMCOM model together with ISL’s own high-fidelity modeling tools for urban sensing and geolocation applications. This model, extensively use by the cellular phone community for urban coverage analysis, incorporates ray tracing and uniform theory of diffraction and a site-specific city data base to make predictions of fast and slow fading, delay spread of signal multipath as well as specific calculations of individual multipath signals. Since future DoD RF Systems will likely have requirements driven by military operations in urban terrain (MOUT), such a modeling capability is an essential component of advanced RF system design and analysis.
