2 Elbit Systems Electro-Optics Proprietary Information

• MUSIC® is a fiber laser-based Directed Infra Red Countermeasure

(DIRCM) system that protects aircraft against ground to air heat

seeking missiles

• MUSIC® rapidly detects, tracks and jams the incoming missile

• MUSIC® can be installed on helicopters, transport aircraft, tankers,

business jets and commercial aircraft

DIRCM Test Stages

• Simulations

• Flight Table

• Flight Tests for laser measurements

• Flight Tests with captive seekers

• Qualification testing

• Live Fire tests

6 Elbit Systems Electro-Optics Proprietary Information

Simulations

• System operational simulation under conditions of:

– aircraft motion

– vibration

– missile ranges

– missile dynamics

• The output of the simulations is the accuracy and distribution

of the laser beam position on the missile seeker.

7 Elbit Systems Electro-Optics Proprietary Information

Flight Table

• Installation of the DIRCM turret on a flight table, acquiring and

tracking a simulated target under the dynamic conditions

relevant to various aircraft.

• The output is the accuracy, power and modulation quality of

the laser beam on the simulated target.

8 Elbit Systems Electro-Optics Proprietary Information

Flight Tests

• Installation of the DIRCM system on a test helicopter type

BO-105

• This was selected because it provides a worst case vibration

scenario

• Acquiring and tracking a simulated target over different

ranges and flight paths.

• The test result is the accuracy, power and modulation quality

of the laser beam on the target.

Flight Tests with Seekers

• Repeat of the flight test using captive missile seekers.

• The seekers are locked on to the signature of the helicopter.

• The DIRCM system is triggered and the time to break lock of

the missiles is measured.

• This test is performed with a number of different seekers

15 Elbit Systems Electro-Optics Proprietary Information

DIRCM Qualification

• Qualification was performed for environmental conditions that

are the maximum of the requirements for rotary and propeller

fixed wing aircraft
