Abstract
There is a need for test equipment to evaluate tracking systems which work in conjunction with laser designated targets. The simulators, which have been built to evaluate the tracking system performance, require pulse laser sources (manufactured by Hughes) in order to achieve the required range of peak pulse power. The simulation includes syntillation, intensity zoom, delayed pulses with amplitude adjustment relative to the main pulse and discrete calibrated power levels of approximate 1 dB increments from 1 to 10-10 peak watts/cm2. The major concern of this paper is to describe a method of simulating the low power levels and a method of determining the calibration error associated with these levels. Brief descriptions are given of the simulator and the operational procedures employed to compensate for the laser source output power drift. Also included are the methods of calibrating the radiometers and attenuation filters. The calibration errors are examined to determine the accuracy of the low power levels. Test results of the correlation between several simulators is given to verify the validity of the accuracy predictions.
