Characteristics

The emitter means we can excite 4 antennas with different frequencies, durations and recurrencies
Useful power up to 100 kW on each antenna
Redundancy of the emitters by means of automatical coupling
LOCAVAR function
Security of personnel and material
The emission bays are compact and modular (7 25 kVA basic emitters installed per bay)
High capacity > 85% for the complete chain
Cooling by means of air coolers in the bays – thermal dissipation in the premises is weak
Wide bandwidth at –3 dB (5 octaves)

The know-how of DEGREANE HORIZON in the field of power electronics has enabled the conception and making a complete emission chain, composed of 16 20 kVA emitters each, operational in the 500 Hz – 10 kHz frequency band.

The anti-submarine warfare is an integrated multisonar system which is installed on the French frigates ASM F67 and where the emitter of the emission subset can drive 3 different antenna types :

  • 2 very low frequency plane antennas in the vessel under tow
  • 1 low frequency cylindrical hull antenna
  • 1 medium frequency antenna in the vessel under tow
