The requirement was to determine the effect of four patching techniques and associated job aids, training, sensor density, and target activity on operator performance in detecting targets when using unattended ground sensors employed in a grid configuration. Trained operators interpreted tactical data recorder RO 376 plots both before and after training using four patching techniques and associated job aids in the grid employment of seismic sensors. The plots represented both 9 sensors per square kilometer grid and 24 sensors per square kilometer grid. Completeness of target detection, number of false alarms, speed estimation error, and target direction deviation were measured. Patching technique training and job aids increased detection completeness by 42 The row patching technique was selected as the best. Use of the 9-sensor grid resulted in fewer false alarms and equal detection completeness as compared to use of the 24-sensor grid.
