PERFORMANCE SPECIFICATION

COMMON LASER RANGEFINDER INTEGRATED CAPABILITY

(CLRF IC)

Scope This specification covers the Common Laser Rangefinder Integrated Capability (henceforth known as CLRF IC) system as a foot-mobile replacement for the Common Laser Rangefinder (CLRF) suite of equipment.

System Description The CLRF IC is a handheld, lightweight, man portable, GPS target location device. The principle function of the CLRF IC System is to assist the operator in determining the location of a target or other object of interest by measuring the distance, direction, and vertical angle from the operator to the object. The CLRF IC System shall also provide the capability to export these measurements (in a suitable digital format) through a serial communications port to external digital devices for further processing. The CLRF IC System shall also assist the operator with day and night target detection, recognition, and identification. The CLRF IC System shall be capable of operating in the full range of environments and operational situations where Marines deploy. Objective requirements that assist the user in target location, detection, recognition, and identification, include the CLRF IC System internal capabilities of laser spot imaging of multiple laser wavelengths.
