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 private customers since 1989.

RFView™ allows users to enter the simulation parameters in a web interface and then submit a job which is run remotely on a high performance computer cluster to ensure timely simulation results. Thus, no special computing software and hardware is required. When the simulation is completed, the user receives an email notification and can view the data on the RFView™ website. The data is also available for download in both Matlab binary format as well as KML format for easy display and analysis using Google Earth.

Our technology 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).

Version 2.0 of RFView™ now provides the user with the capability to easily set up a simulation with multiple CPIs along a flight path as well as provides a capability to simulate a bistatic scenario.

ISL’s Real-Time Electro-Magnetic Environmental Simulator (RTEMES) let’s you take advantage of ISL’s industry-leading RFView simulation capability when testing your actual flight hardware. With RTEMES you can fly your RF system (radar, ELINT, EW) anywhere in the world under the most stressing conditions that would otherwise not be possible or affordable!

“Why pay for expensive flight testing when you can see how your system will perform anywhere in the world without leaving the lab!”

“Operators can now train using the actual radar hardware!”

Coolant level monitoring is necessary for nuclear reactor safety and reliability, and the current need is to monitor small modular reactor (SMR) designs.  Safety and reliability are compromised by using current invasive sensors, such as pressure gauges, that penetrate the reactor and containment vessels (RPV and CNV).  ISL has invented a non-invasive sensor (GraviSense™) that can measure coolant level to 3 cm accuracy using super-sensitive gravimeters that sense the mass distribution of the coolant from outside of both vessels.  Because GraviSense™ will be outside of the CPV in a SMR reactor pool, it can be maintained and replaced without disturbing the pressure vessels, contrary to the operation of invasive sensing methodologies.

Innovations:

  • Doesn’t measure a point field such as pressure or thermocouple, but measures the effect of the entire mass distribution and records changes over time!
  • Non-invasive to the internal pressure spheres of both the RPV and CNV!
  • Entirely passive and non-threatening to employees, in contrast to methods such as gamma rays!

Use of GraviSense™ will reduce reactor down-time and lead to cost savings, because the sensors can be replaced one at a time for maintenance without interrupting the power cycle!

GraviSense™ will be able to determine if a Loss-of-Coolant accident (LOCA) has occurred (Figure 1).

Figure 1 – Concept for using GraviSenseTM for measuring loss of coolant (LOCA) in a small modular reactor (SMR).  The coolant in the inner reactor pressure vessel (RPV) changes its mass distribution during a leak, which the two gravity sensors measure as a change in gravity with time. 

ISL researched GraviSense™ in a DOE STTR Phase 1 using the NuScale NIST facility at Oregon State University, with excellent results that confirm its ability to resolve coolant level changes (Figure 2).

EA-buoy Combination Sonobuoy for ASW

Modern diesel-electric submarines pose a threat to national maritime strategy and naval operations. ISL has invented a new air-launched sonobuoy for anti-submarine warfare, which will give the Navy a greatly enhanced capability for localization and small area search operations against these quiet diesel-electric submarines, particularly in littoral waters. The high-altitude of the P8A aircraft makes localization using traditional Magnetic Anomaly Detection (MAD) difficult. The traditional method of flying low over a suspected threat to localize it using an onboard MAD sensor can no longer be part of the concept of operation (CONOPs). This factor, combined with the limitations in passive acoustic sensing, create an overall problem in the CONOPs for localization. A new passive sensing technology is thus needed to maintain an effective anti-submarine warfare (ASW) capability for Naval operations, which ISL has developed….(Learn More)

MANTA

MANTA is a passive acoustic intercept SONAR system providing long-range detection, tracking, and real-time data analysis capabilities, in a compact and low-cost footprint.  The intercept portion provides submarine crews with the capability to detect, track, and classify the full range of active sonar signals from ASW ships, weapons, and other submarines in order to make rapid tactical decisions.  A full 360 degrees of bearing coverage is provided using a 16-element cylindrical hydrophone array, and frequency response up to 100kHz allows detection of ASW sonars, ASW weapons, side scan sonars, underwater communications, and fish finding sonars.  Optional ranging hydrophones can be added to enable the range estimation of a target from a single intercepted pulse.  The frequency analysis portion of the system supports detailed passive hydroacoustic analysis and recording of signals from the intercept array and other sensors on the submarine.  The frequency analysis system features a flexible and intuitive graphical user interface with extensive analysis and display tools.
