Sorry this is in French.

On 11 of June the french CEAM (military air experimentation centre) successfully tested a new kind of shooting.
A Rafale F2 shot a target behind him (and killed it) thanks to data transmitted from another Rafale with Link 16.
The missile used was a Mica EM (active radar seeker). This missile has thrust vector control and can be fitted indeferently with IIR or active radar seeker, and can be shot BVR  (30 NM, maybe more, depending on launch conditions) or in close combat with a helmet cueing system.

The Rafale has also recently demonstrated that it has multitarget capability in air to ground role, with AASM. It can shoot at 6 different targets in one pass. One of the firing was nearly 90° of aircraft flight path.
The AASM is a kit with GPS guidance and rocket engine, fitted on Mk 82 bomb, giving it around 15 km range on low level firing and more than 50 km at high altitude.

The Rafale features a fully integrated digital avionics suite with a modulare core architecture:

MDPU:
The modulare data processing unit (MDPU) form the heart of the Rafale's avionics. It's a modulare mission computer cmprising 18 processor modules. The MDPU is said to be 50 times faster than the Mirage 2000-5s mission computer and hosts the software for most of the aircraft's systems and avionics.

Networking:
The avionics integration is assured by linked the various systems to each other via at least 4 digital MIL STD 1553B databusses and at least 1 optical STANAG 3910 datbus. Communication between the aircraft's onboard systems and its weapons is enabled by 2 digital MIL STD 1760 databusses.

Recording:
The Rafale's recording systems include a Thales ESPAS digital solit state flight data recorder and a OTA 1320 CCD TV camera plus recorder for HuD video footage. The recording systems record maintainance data as well.

IUHMS:
The integrated usuage and health monitoring system (IUHMS) features fully integrated and automated built in test equipment (BITE) along with sensors and digital recorders for airframe structure and engine components life monitoring.

Navigation:
The Rafale's navigation suite includes two Sagem RL-90 LINS platforms with embedded NSS-100 GPS receivers. The LINS allows flight plans with up to 600 waypoints being programmed and stored.
Addiotnal navigation equippment includes the NC-12E TACAN radio navigation system, the TLS-2020 multimode receiver which includes VOR and ILS/MLS functions, a digital map generator (DMG), a digital terrain reference navigation system (TRN) and the digital AHV 2930 radar altitmeter which is optimised for discretion and high performance at very low altitudes. The radar altimeter works at altitudes up to 3200 m.

Communication:
The communication equipment comprises EAS TRA 2020 V-/UHF radios for civil communication and secured TRA 6032 V-/UHF radios for tactical military communication, compatible with HQ I & II and SATURN standards. The aircraft additionally features the MIDS-LVT/LINK16 bi-directional data link terminal for secured and jamming resistent near real time communication and data exchange.

Autopilot:
The known Autopilot modes include:
- Flight path tracking
- Altitude hold modes
- AoA hold mode
- Auomatic terrain following
- Auto throttle

Self Defence:
The Rafale's SPECTRA (Système de Protection et d'Evitement des Conduites de Tir du Rafale – Self Protection Equipment Countering Threats of Rafale Aircraft) is one of the most advanced EW suites ever created for a combat aircraft. Being of a modulare design, SPECTRA is controlled by the GIC computer (Gestion de l'Interface et Compatibilité) comprising 3 processors.
The SPECTRA components include:
- 3 digital RWR antennas with each 120° azimuth coverage and a frequency coverage of 2 - 40 GHz mounted on the airlift intakes and at the rear of the SPECTRA fin tip pod. Functions/characteristics include:
  - detection localisation, identification and priorisation of radar emitters at distances up to 200 km+
  - Bearing accuracy below 1° in azimuth using interferometry
  - Weapon cueing against ground based emitters
  - ELINT/SIGINT

- Active ECM system with DRFM and AESA antennas in the canard roots and in the tail pod at the base of the fin, with offensive, defensive and stealthy jamming modes. Pencil thin jamming beams are directed towards threat emitters

- DDM (Détecteur infrarouge de Départ de Missiles) missile approach warning system based on dual-band midwave IR sensors which are located on each side of the SPECTRA fin tip pod, providing 360° atimuth coverage

- 3 DAL (Detecteur d’Alerte Laser) laser warning receivers with sensors on the fuselage sides and the rear of the SPECTRA fin tip pod

- 4 vertical firing flare/decoy dispensers on the top of the fuselage near the wing trailing edges and 2 chaff dispensers on the rear fuselage sides behind the wings

Note:
The RWR and ECM systems are integrated as the DBEM (Détection et Brouillage Electromagnétique) sub-system.

Radar:
Thales RBE2 (Radar a Balayage Electronique – deux plans) is a modulare designed monopulse-doppler X-band multimode fire control radar system. It features 4 LRI including:
- ~60 cm PESA antenna
- 4 channel receiver
- transmitter
- programmable signal processor with at least 2 bln flow point operations/second

The RBE2 provides a +/- 60° azimuth and elevation coverage and includes the SB-25A MkXII compatible IFF interrogator/transponder with Mode-S capability. The IFF system uses phased array antennas.

Air to Air modes/functions include:
- Long range search
- Multi target track and engagement
- Air combat modes
- NCTR
- RAM
- Look down/shoot down

In AA mode the RBE2 offers a tracking range beyond 100 km against a 3 sqm target with detection ranges up to 130-140 km. The radar can track and prioritise up to 40 targets simultaneously, engage up to 8 of them and provides McG for up to 4 missiles. It includes LPI characteristics and as capable of track here while scan there.

Air to Ground modes includes:
- DBS mapping
- SAR mapping
- FTT
- SEA surface search and TWS
- GMTI/T
- TA
- AG ranging

Terrain following and avoidance modes can be combined to generate 3-D radar maps, which enable automatic terrain following flights via radar. AA tracking and AG mapping can be interleaved due the radars agile beam sweeping capabilities.

Electro optical systems:
The OSF (Optronique Secteur Frontal) comprises two modules on the aircraft's nose. The right one features an imaging dual-band IRST/FLIR sensor (3 - 6 and 8 - 12 microns) and the left one, aka CIU (Combat Identification Unit) features a 3-D CCD TV camera and a laser range finder.
The IRST provides a +/- 90° azimuth coverage and is capable to detect and track multiple aerial targets simultaneously. The sensor offers a max. detection range of 130 km in best conditions and can act as FLIR providing target images up to ~40 km and nav-images presented on the HuD.
The TV camera offers a max FOV of 60° and a range of ~50 km for single target track and identification. The LRF is effective up to ranges of 33 km.

Sensor fusion:
All the Rafale's onboard and offboard sensor data are fused, creating track files which contain correlated data from all the aircraft's sensors and which are presented on the large Head Level Display.
