THORONDIR

THORONDIR: SOFTWARE FOR REAL-TIME RADAR CLASSIFICATION IN ESM SYSTEMS.

THORONDIR is artificial intelligence software for radar identification in ESM and RWR systems. It uses an “Open Systems Architecture” approach based on the use of industry standards such as TCP/IP to interface with the rest of an Electronic Warfare suite. It is derived from software that is used in the Royal Navy’s front-line ESM systems but is also applicable to airborne RWR systems.

THORONDIR APPLICATIONS

THORONDIR is targeted as a replacement for conventional identification software in ESM and RWR systems for a range of platforms from patrol craft to aircraft carriers and from attack helicopters to fast jets.

OPERATION

THORONDIR matches deinterleaved and characterised intercepts from a radar ESM receiver against a database of radar emitter parameters. The system reports radar identifications in real-time – usually matching a unique identity for each intercept. Knowledge about radar characteristics and ESM failure modes are encoded as ‘rules’ in a flexible knowledge base.

FEATURES

THORONDIR is targeted as a replacement for conventional identification software in ESM and RWR systems for a range of platforms from patrol craft to aircraft carriers and from attack helicopters to fast jets.

R

COTS standalone software that can be embedded in an ESM or RWR system.

R

Industry leading identification accuracy with very low ambiguity.

R

Fast, real-time identification.

R

Can be run on a standard PC platform or be integrated into an embedded system on standard processor cards.

R

Designed for ease of integration.

R

Can model the latest, complex, modern radar emitters.

R

Supports separate, extendable library of radar signatures.

PERFORMANCE

R

Greater than 75% correct and unambiguous identification with less than 6% incorrect identification in scenarios with high parameter ambiguity.

R

Average identification rate of greater than 10 intercepts/sec for a single instance of THORONDIR on an Intel i3 2.4 GHz with 5000 mode mission library.

R

Maximum latency for individual intercept identification is 3 seconds whilst maintaining average identification rate with 5000 mode mission library.

PACKAGE

THORONDIR is currently available for Windows and Linux on a range of processor platforms and provided with comprehensive documentation of the API and library format. The software can be provided with a commercial radar emitter library although performance is not guaranteed with this library; comprehensive integration support can also be provided. Offline performance analysis software is available to support the building of emitter libraries.

UPGRADES

THORONDIR is constantly evolving in response to customer requirements and licencing can include a maintenance package that provides regular upgrades. ESROE is currently developing a ‘generic’ identification capability that can indicate the function performed by an intercepted radar without requiring a library to be loaded.
