The DHY 307 ground laser target designator belongs to the Modular Illuminating Range Finders (TIM) family developed by CILAS.
Intended for use by small ground units, it provides precision guidance for any missile, bomb or shell fitted with final laser guidance targeting an individual tactical objective.

Presentation

Portable and with very flexible usage, it makes “laser-guided strikes” available to units that cannot employ an on-board designator (pod) due to high integration costs.

Characteristics

The requirements for light weight, efficiency and protection of the illumination codes were the basis of the design of the DHY 307 designator and led to the following definition of the subassemblies that comprise it:
– An illuminator unit made from modules that are common to all range finders/illuminators in the CILAS TIM family, which includes the elements needed for target illumination.
– A control box connected to the illuminator unit by a short cable that is used to:

• select an illumination code from the pre-recorded codes
• control the various operating modes
• initialise
• launch the integrated test
• control the thermal security inhibition
• verify the battery’s charging
• fire the shot without losing aim.

– An independent power supply that guarantees a functional timeframe that is compatible with operational requirements (battery or vehicle power system).
– A tripod fitted with an optical goniometer that indicates the target’s site and directional angle.
– The various connection cables between the illuminator unit, the control box and the independent power supply.

This assembly weighs less than 13 kg, resulting in very flexible usage. With its low divergence laser beam, this equipment is difficult for the enemy to detect. As such, it is relatively unaffected by current jamming and decoy techniques.

Wavelength: 1.064 µm
Magnification: x 7
Laser protection: 53 dB at 1.064 µm
Dioptre adjustment: + 2 to – 6 dioptres

Applications

The DHY 307 is the ideal target designation system. Light and compact, it has been designed to control all types of weapons with final laser guidance.
The efficiency and flexibility of ground laser designation provides for a much broader range of applications: tactical support with L.G.B., target marking for aircraft equipped with laser deviation measurement systems for conventional weapons.

The mission on the ground takes place in three steps:
Identification of the target and aiming of the designator at it, followed by selection of one of the pre-programmed codes;
Coordination with the launcher of the laser-guided weapon for initiation of the illumination operation;
Illumination of the target until impact.
