DESCRIPTION

ATMF is designed for use with the TM-62 and TM-72 series anti-tank mines to enhance their performance. It incorporates a small shaped charges to penetrate armour and thereby substantially increase the lethality of the parent mine.

ATMF is one of the most powerful anti-tank mine fuzes available today. The combination of a multi-sensor system, sophisticated signal processing and high explosive power offers an outstanding overall performance. Hit probability and destructive power are unrivalled.

ATMF OPERATIONS

ATMF is screwed into the central threaded fuze well of TM-62 /TM-72 series anti-tank mine when the mine is laid.

Arming is performed by unlocking the arming lever lock and thereafter moving the arming lever into the arming position, thereby opening the explosive train. Firing capacitors remain discharged until end of arming delay, the detonator is short-circuited until immediately before firing.

A status LED at the top side of ATMF informs the operator about the condition of the fuze: not armed-in arming delay – last minute of arming delay – error in fuze.

During operational life of the fuze the LED is switched off.

ATMF uses combined seismic, electromagnetic and force influence sensors to identify its target and select the optimum moment for initiation.

On initiation, a clearance charge removes earth from above the fuze before the shaped charge is detonated. The shaped charge forms an EFP (explosively formed projectile) that penetrates the belly armour of the target vehicle and initiates the charge in the TM-62/TM-72 mine.

DEPROG

DEPROG enables the user to program, deactivate and activate ATMF from distances up to 0,5m.

DEPROG is designed for highest possible safety and consists of the electronic unit, the probe and an optional headphone.

The probe communicates with the ATMF in a bidirectional way: a command sent to the fuze has to be acknowledged by the fuze. Thereby it is assured to the user of the device, that ATMF really understood and accepted the command, which is especially important in case of deactivation command.

The operational parameters for ATMF, operating time and numbers of by-passings, may be entered into the DEPROG using its panel controls or from an external PC via the built-in USB port.

A 16×2 character LED display at the front panel of DEPROG supports the user.

The device has to following functions:

  • Program operational life time of the fuze
  • Program number of by-passings of target vehicles
  • Quich change of fuze settings
  • Search operational camouflaged ATMF
  • Inquire status of ATMF: operating time, activated / deactivated
  • Deactivate / Activate the ATMF
