Compromise, modularity and integration
Characterization of the threat and the imperatives of development costs resulted in a compromise between the various parades available on a combat aircraft:
- avoidance leading to preventive techniques of signature reduction, terrain-following and path optimization in mission planning
- by avoiding detection and trajectory modification, which allows to adapt pro-actively in real time
- avoidance leading to neutralization by various techniques of jamming and decoy, when the previous parades have failed
Spectra is the result of a compromise that complements real-time actions to reduce infrared and electromagnetic signatures applied to the cell and equipment of the weapon system, the automatic flight at very low altitude, and the function control of the tactical situation to which all contribute on-board sensors and data transmission network MIDS.
To ensure the functions of detection, jamming and deception in the areas broadband electromagnetic, infrared and laser
, the choice is focused on a self-protection system modular and fully integrated. The modularity of Spectra is to distribute, in various parts of the wearer, sensors and transmitters diverse, working in the different spectrum in the face of multiple threats: electromagnetic radiation and infrared radiation, detection of missile or laser illumination. The main innovation is the ability to locate a threat with an accuracy of five to ten times higher than conventional systems
, in order to adapt the manoeuvring, jamming or spoofing applied. Due to the complexity of the whole, a high degree of integration is necessary, so that the weapon system analyses all the elements before proposing a solution to the crew.
With Spectra, the Rafale has a self-protection system that goes beyond current counter-measures systems. Sensor fused with all components of the navigation and attack systems contributing to the discretion of the aircraft, Spectra provides the crew with a comprehensive tool for analysing the air-to-air or air-ground threat in real time, and neutralization of aggression by the most effective means available on board
. Spectra not only significantly improve the survivability of the Rafale, it directly contributes to greater efficiency in accomplishing the mission.
