System IDAS / CIDAS SAAB (Brazilian Air Force)
The Integrated Defensive Aids Suite (IDAS) or S uite Auxiliary Equipment Integrated Defense Swedish of SAAB , is responsible for peripheral self-protection H-225M and aims to increase their ability to survive in modern conflict scenarios, consisting of sensors working alerting with advance to the crews of radar, laser emission and hostile missile threats.
MAW-300 (Missile Aproach Warning)
The missile approach, works the UV spectrum (Ultra Violet), through special filters with capacity to “capture” photons (wavelength) at long distance. Using what the manufacturer calls the “neural classifier network,” it works with the positioning of the platform in space with respect to its in-flight displacement, using the aircraft’s native INS / GPS data, allows, once a threat is detected , its discard when it is a false alarm, or when valid, it classifies its degree of risk, projecting, by probability, the future trajectory of the missile, being able to trigger defensive measures with Flare / Chaff directing to the threat. Each sensor that has a field of action in 110º, has its own processor, uses digital signal with hierarchical architecture of data processing, to optimize information in real time. The data of each sensor, which can detect and process multiple potential targets, is transferred to a digital control unit (MAW controller) in the Electronic Warfare Controller (EWC). Four sensors are used in each quadrant of the helicopter, providing 360º coverage, two front and one above the pilot / co-pilot window and two behind, at the end of the main landing gear fairing in a triple conjugate station with two more sensors ( LWS-310 / RWS-300).
LWS-310 (Laser Warning System)
System laser Alert , is operable using four sensors connected to EWC (Electronic Warfare Controller), hardware responsible for processing data obtained by sensors. The LWS-310 sensor is an arc-shaped cube containing eight multidirectional mini-windows with a large angular aperture and capable of reading 0.5-1.7 μm (microns) wavelength , with high sensitivity to various lasers. It can classify threats as laser rangefinders , designators and lasers used for missile guidance with an embedded system that has data library. Like the MAW-300, the LWS-310 is installed in the quadrants of the H-225M, being in the back in the triple station, in the front is in dual station conjugated with the RWS-300 sensor on the sides near the junction of the radar dome.
RWS-300 (Radar Warning System)
System Radar Warning is composed of the RWS-300 sensor, it is the antenna (SAM Spiral Antenna Module) card , an antenna spiral shape covered by a cylindrical hood, is capable of approved varying electro-magnetic emissions simultaneously with set range between 0.7-40 GHz (pulse radar) and 0.7-18 GHz (counter measures) frequency. It has the same operating principle of the MAW system using the EWC (Electronic Warfare Controller) can trigger the defensive systems of the helicopter in case of detection of threats.
BOP-L (Countermeasures-dispensing function)
Dispensador Counter-measures , shaped device shelter (box) that is installed on each side of the helicopter tail cone. In an internal drawer is the pyrotechnic ejection loads of CHAFF and FLARE, electronically driven. CHAFF has the function of trying to confuse the firing radar system that makes up the ground anti-aircraft batteries or guidewires that are embedded in the missiles that are engaging the helicopter. When a critical radar threat is detected (missile coming in), shelter charges that blow up in the air are ejected, releasing up to thousands of ultra thin blades forming a cloud, made up of metals or special material with properties to better reflect radar waves, can to simulate fake targets for an acquisition system, with a great chance of diverting the radar-guided missile into the aircraft. FLARE is intended to attract and divert missiles with heat guidance (IR). Composed of white phosphorus (WP) material, when ejected from its capsule and due to its chemical properties, it is in high combustion in contact with oxygen, producing intense heat, the heat produced can confuse the IR missile seeker in pursuit by diverting it, in evasive maneuver, several charges are launched simultaneously to increase the chances of success. The BOP-L can be easily replenished by changing the drawer, has a low weight, can be pre-programmed in the sequence, BIT (check ground), and can carry up to 32 loads. Source portaldefesa.com
