IMT Overview IMT is the scientific and engineering technology partner to the SA Navy. We are the Navy’s “Battle Lab” conducting relevant research and capability - building to allow us to: • Understand technology areas to provide the Navy with educated and objective advice. • Support the Navy to resolve operational deficiencies with Applied Technology & Research. • Conduct independent Maritime Test and Evaluation. IMT also provides R&D marine engineering and sciences, applied maritime technologies and utility to the South African National Defence Force (SANDF), defence industry, the Oceans Economy and other commercial clients.

Relevant Technologies (1/5) Radar Scan Converter Technology • IMT developed Radar Scan Converter digital hardware and display software. This allows interfacing to any radar to extract the plots and track targets. This is used for Maritime Domain Awareness (MDA) and can be used for other surveillance radar applications as well. Aerial Drone Intercept Technology • IMT is in process with a Technology Demonstrator that can detect Commercial-off-the-Shelf (COTS) drones and deny the operator control of the drone. Requirement Analysis, System Conceptualisation and Test & Evaluation • Although not a technology, IMT has significant capability in this regard. Electro-Optic (EO) Sensor Technology Demonstrators & Performance Modelling • Developing integrated small electro-optic sensor technology demonstrators for optimized surveillance using Commercial-off-the-Shelf (COTS) components. Examples include harbour / area surveillance camera systems and long range identification systems. Thermal Infrared Signature Analysis and Simulation • IMT developed optimized software for thermal infrared signature analysis and modelling / prediction. A DIVISION OF ARMSCOR SOC LTD
Relevant Technologies (2/5) Sentry Buoy • A moored or free floating buoy that triggers when prescribed thresholds (e.g. acoustic) is exceeded and then relays the information via Radio Frequency (RF). The recipient can then listen in on the audio that is sensed by the buoy. This would be suitable for protection of military or environmentally sensitive areas. Submarine Emergency Signalling & Satellite Communications Buoy • An Emergency Signalling Buoy was developed for release from a stranded submarine. A message is saved on the buoy from a laptop computer via a Bluetooth link. The buoy is then released through the submarine signal ejector. On surfacing the message is transmitted via Iridium satellite to up to 5 pre-programmed emails. • The current enhancement is to also link the buoy to an Iridium satellite voice channel. At the same time the buoy links to the submarine underwater telephone via an acoustic signal to establish a direct voice telephone link from the submarine to any telephone number. Retractable Autonomous Buoy • Development of a Shallow-Water Retractable Autonomous Buoy. The buoy will monitor and record data from the ocean floor or predetermined depth, and rise to the surface to transmit the data. It will then retract itself autonomously.

Relevant Technologies (3/5) Passive Sonar Target Analysis and Classification Technology • Automatic Sound Classification technology is being developed to perform sonar target sound analysis and classification to assist sonar operators and shore sonar signal analysts. The continuous underwater radiated noise as well as transient underwater noises can be analysed and classified. The algorithms are being evaluated by the SA Navy and IMT. The sound analysis tools are also used for sound ranging and fault diagnostics in the propulsion systems of naval vessels. Underwater Locator Beacon Detection Algorithms • A novel detection algorithm is being developed to detect the very short pulses typical of aircraft underwater locator beacons (“Black Boxes”). The algorithms are deployed in a notebook computer that is the man machine interface of the Underwater Locator Beacon Detector demonstrator system. A DIVISION OF ARMSCOR SOC LTD
Relevant Technologies (4/5) Semi-Autonomous Remote Operated Vehicle for Hull Scanning • The Remote Operated Vehicle (ROV) was developed to autonomously scan a requested section of the hull, stitching the close-up camera frames to supply a large image. • This requires exact automated navigation and attitude algorithms in order to scan the surface. For this purpose, underwater lasers and image recognition algorithms were developed. Geospatial Technology Capability • Geographic Information System (GIS) technologies applied within Maritime Domain Awareness. • Hydrographic Geospatial Technologies for the development of Additional Military Layers for Electronic Charts. Maritime Rapid Environmental Assessment (MREA) • This capability / technology was developed for the South African Navy for “The timeous collection, analysis and provision of tactically and operationally useful environmental data, within a tactical time scale, to achieve battlespace dominance” .

Relevant Technologies (5/5) Electric Shark Barrier • Under contract from the KwaZulu-Natal Sharks Board an electric shark barrier was developed. The barrier consists of a cable on the sea floor with regular spaced electrodes rising to the sea surfaces. The system emits electric pulses with a specific shape to deter sharks from entering an area. It does not influence other fish and is safe for bathers. A DIVISION OF ARMSCOR SOC LTD

Surveillance & Keypoint Security (7/8) Underwater Surveillance • IMT operates a REMUS 100 AUV. • The REMUS 100 AUV can be configured to include a wide variety of standard and/or customer-specified sensors and system options to meet unique autonomous mission requirements. 15 A DIVISION OF ARMSCOR SOC LTD
Surveillance & Keypoint Security (8/8) Underwater Surveillance • In process with low-cost COTS-components diver detection technology demonstrator. • Also evaluating Diver Detection Sonar products. 16 A DIVISION OF ARMSCOR SOC LTD
Maritime Domain Awareness (1/12) MDA is the effective understanding of anything associated with the maritime domain that could impact the security, safety, economy, or environment of the nation. MDA is a key component of an active, layered maritime defence in depth. A DIVISION OF ARMSCOR SOC LTD
Maritime Domain Awareness (2/12) Vistanet Ocean Shipping Traffic Monitoring System • Vistanet is a software system managing coastal networked shipping traffic sensor data . IMT has been developing the software system over the past 2 decades. It performs data collection , data packing , data storage , display and analysis . Shipping data is collected from sensors along the South African coastline into a data centre and then distributed for display and analysis in various locations. • The uniqueness of the system lies in the mature and flexible networking and software components .
