LIN: D04638

GENERAL:

The AN/AVR-2 LDS is a passive laser warning system which receives, processes and displays threat information resulting from aircraft illumination by lasers. The threat information is displayed on the AN/APR-39A(V)1 Radar Signal Detecting Set indicator in the cockpit.

PHYSICAL CHARACTERISTICS:

The AN/AVR-2 LDS consists of one interface unit comparator and four identical sensor units. The total system weight is 21 pounds.

THREAT COVERAGE:

The AN/AVR-2 LDS responds to lasers associated with laser range finders and laser guided weapons.

AIRCRAFT APPLICABILITY:

AH-1F

SPECIAL TEST EQUIPMENT:

TS 4321/AVR-2 Test Set, Laser Detecting (AVIM)

GENERAL:

The AN/AVR-2A LDS is a passive laser warning system which receives, processes and displays threat information resulting from aircraft illumination by lasers. The threat information is displayed on the AN/APR-39A(V)1 Radar Signal Detecting Set indicator in the cockpit. The AN/AVR-2A LDS is derived from the basic AN/AVR-2 LDS through the incorporation of several engineering change proposals (ECPs). These ECPs include: incorporation of the Multiple Integrated Laser Engagement System-Air-to-Ground Engagement System interface; incorporation of a removable user data module to the comparator interface to permit a means to apply software changes and system declassification; and increased Band III sensitivity for improved threat detection performance.

PHYSICAL CHARACTERISTICS:

The AN/AVR-2A LDS consists of one interface unit comparator and four identical sensor units. The total system weight is 21 pounds.

THREAT COVERAGE:

The AN/AVR-2A LDS responds to lasers associated with laser range finders and laser guided weapons.

AIRCRAFT APPLICABILITY:

AH-64A/D, MH-47E, MH-60K, OH-58D, EH-60A
