SAAB : IDAS EW Suite
Vol 10 Issue 6 Jan - Feb 2017
Monday, February 6, 2017
To survive the modern battlefield, military aircraft requires self-protection systems that is capable of detecting the threat, indicating the presence of the threat and ensure that the appropriate countermeasure is activated in order to successfully defeat the threat. The self-protection system need to operate in an environment emissions cluttered environment and as it is not normally deemed prime mission equipment need to be low in terms of size, weight, power and cost.
Saab’s Integrated Defensive Aid Suite, commonly referred to as IDAS, is an Electronic Warfare (EW) self-protection system specifically designed for use on airborne platforms. Unlike other federated EW systems, IDAS is fully integrated and requires only a single controller to perform radar warning, missile approach warning and laser warning. The controller provides visual and audio information to the aircrew and in addition controls the counter measure dispensing system. Fully integrated does not only mean that all these functions are controlled from a single controller but the IDAS system also includes the tools required to program the threat libraries, countermeasure dispensing sequences and analysis of onboard EW recordings.
Being a fully integrated system allows the support of the complete EW system to reside under one roof. This greatly benefits the end user in that the support the entire system is secured for its intended operational life.
The single system controller provides for a low system box count and lightweight package with exceptional performance. Despite its integrated design, its modular system architecture allows for IDAS to be configured in any combination of the three sensor types as user requirements may dictate. CIDAS (Compact IDAS) is a variant of IDAS and is a configuration that excludes the radar warning system functionality. CIDAS is particularly suited for smaller platforms where size and weight are restricted.
The radar warning system detect Radiofrequency (RF) signals emitted from radars that form part of an integrated air defense system, alerting the pilot to a possible enemy position. The type of radar used the mode of the radar and direction and range of the threat is displayed to the aircrew. The radar-warning function features a compact, wide-band, high-sensitivity solution with high probability of intercept (POI).
The laser-warning functionality features high sensitivity, excellent threat coverage and exceptional probability of intercept (POI) for both single and multi-pulse emissions. A unique feature of the LWS-310 is that it not only classifies laser emissions, but can also identify laser emission through a user-programmable threat library thereby classifying the type of laser threat as either a rangefinder, designator, beam rider or dazzler.
The MAW-300 missile warning sensor features a unique optical design that ensures high sensitivity equating to long detection range. Each sensor uses a dedicated digital signal processor making use of a distributed, hierarchical data-processing architecture to ensure optimal utilisation of information in real time. The MAW-300 sensor is in production for numerous platforms. It has been field tested and verified against numerous live missile firings under in-flight dynamic conditions. The angle of arrival information accuracy of the MAW-300 is suitable to cue a Directed Infrared Countermeasure (DIRCM). Integration with the Miysis DIRCM was successfully demonstrated as part of the SALT II (Surface-to-Air Trail II) live-fire trial hosted by FMV at Vidsel in Sweden during May 2014.
The BOP-L Countermeasure Dispensers (CMD) are controlled via a fully integrated chaff-and-flare dispenser controller that resides in the IDAS system controller. Manual, Semi-Automatic and automatic modes are available to the aircrew. The automatic mode allows for immediate dispensing upon threat-identification according to the pre-defined EW library. The dispensing techniques can be defined in the threat library for the EWC and uploaded to the system on the flight-line. The jettison of all payloads is possible in all modes of operation under emergency conditions.
The CMD system can handle mixed payloads per dispenser and accommodates the dispensing of covert Infrared (IR) countermeasure flare.
The IDAS system is fully supported by dedicated flight-line stimulators for each type of sensor and chaff-and-flare test blocks (CFTB) for the dispensers. Apart from O-level support, the flight-line test equipment is capable to verify system serviceability prior to mission take-off.
IDAS has achieved outstanding operational success with a growing list of customers in Europe, Asia, Africa and the Middle East. The product has been ordered/installed on helicopters, commercial transport aircraft as well as fighters. Platforms on which IDAS has been installed include Oryx, Puma, Cougar/Super Puma, Rooivalk, A109, Super Lynx 300, Dhruv, Chinook, Hawk, C-130, Su-30, NH-90, Embraer 120, Gripen, Saab 2000 & ERIEYE, Dash-8 and Tornado.
Saab’s IDAS system has been selected as the electronic warfare self-protection system for the Indian Army’s and Air force’s Advanced Light Helicopter (Dhruv). Saab has signed a
Long Term Business Agreement with HAL for the supply of IDAS and will include the transfer of technology of the system.
