Comparison of Three Display Devices for Unattended Ground Sensors.

摘要

Requirement is given to determine the relative values of the operational RO 376 event recorder, a situation map display, and the use of time compression with the situation map display for displaying activations of seismic unattended ground sensors under typical operational conditions affecting the interpretation of these displays. Three tape recordings, each 2 hours long, of the activations of unattended ground sensors were compiled from the data bank of recordings of unattended ground sensor activations taken during Project 1030 and BASS III tests at MASSTER. Typical patterns at two levels of target activity were selected for personnel and vehicular targets. Aircraft, artillery, and background noise were added to simulate operational noise. These recordings were played back to activate the three displays. Use of the operational RO 376 resulted in higher accuracy and completeness of reports than did use of the other displays. Ni differences were found between the situation map display and the situation map display with time compression.
