Fast Time Analysis System (FTAS)
ISL's FTAS systems incorporate cost-effective, Commercial-Off-The-Shelf (COTS) hardware and software selected for faster data handling and increased storage capacity. They are becoming the standard for affordable, COTS-based, open architecture, post mission analysis systems for NATO and nations with maritime surveillance capabilities.
The FTAS provides the analyst with display and post processing tools for performing detailed analysis of both passive and active acoustic signals recorded from all sonobuoys deployed by operational Maritime Patrol Aircraft or Helicopters. The scalable system is based upon a flexible, high performance single chassis digital signal processor unit interfaced with multiple PC-based display and control workstations over a high speed local area network. The system accepts acoustic data in a variety of digital and analog inputs including STANAG 4283 compliant analog and digital formats.
With the system’s flexible and intuitive graphical-user interface, including extensive analysis and display tools, tasks can be programmed to work within a number of well-known, commercial operating systems. The operator workload is significantly decreased through the application of massive acoustic data storage capabilities that allows the original data to be replayed once from the original tape or data source and then analyzed many times from memory at a variety of replay speeds. The open system architecture supports expansion and upgrades to accommodate additional or improved signal processing hardware, emerging operator analysis tools, and new requirements of the littoral or open ocean operating areas.
These systems are currently in operation supporting the Maritime Patrol Air (MPA) Navy communities in The Netherlands, France and Germany.
Submarine Intercept and Analysis (IntAna) System
The IntAna system is a compact, low cost, open architecture, COTS-based intercept and analysis Sonar designed for installation on submarines operating in high density acoustic target/threat environments. IntAna provides submarine crews with real time capability to detect, track, and classify the full range of active sonar signals from surface ships, submarines, and underwater weapons for rapid and accurate tactical decision making. The 500 KHz acoustic bandwidth is the widest available in today’s market. Covering the frequencies of all ASW sonars, weapons, side scanning sonars, underwater communications devices, diver sonars, and fish-finding sonars, the IntAna system supports detailed passive acoustic analysis and recording of signals from numerous and varied passive sonar arrays and sensor configurations.
IntAna systems feature a flexible and intuitive graphical-user interface with extensive analysis and display tools that run under an advanced, commonly used operating system. The system processing and display software can easily be integrated into current or future combat and weapons control systems. Originally developed for the Royal Swedish Navy and currently deployed on several of their submarines around the world, IntAna systems are now being evaluated by several other countries for integration into their submarine combat systems.
Fast Spectrum Analyzer
ISL has a long history of developing and producing a line of Fast Spectrum Analyzers operated by the Signal Intelligence (SIGINT) community to perform detailed analysis of Radio Frequency (RF) signals. Several thousand of the products have been produced over the years and are integrated into analysis laboratories and field sites operated by government agencies around the world. 
The current version of this product operates in the spectrum between 10 Hz and 16 MHz and offers the operator an advanced signal processing, high-resolution display and a full set of advanced analysis features and tools.
