Abstract:

This report analyzes data collected from Field Experiment 43.8, the ground-to-air visual detection experiment. Phase IIA was a one-sided experiment using AH-1G and OH-58 helicopters for detection at ranges from 1 to 5 kilometers by ground observers with unaided vision. The experiment provided data on the time required for a ground observer to detect an observation helicopter, an attack helicopter AH, or an attack helicopter team AHT and the frequency of detection for each configuration while situated in a firing position. Independent variables tested in the experiment were range, search sector, canopy or no canopy helicopters, lateral or no lateral movement, sky or terrain background, single ship or helicopter team presentation, and for multiple pop-up tactics, elapsed time between first and second pop-up, and location of the second pop-up with respect to the initial pop-up. Data gained from this experiment, when coupled with data from Phase IIB, the air-to-ground experiment, will produce information required to develop helicopter employment tactics. Detection time determined from the analysis of the data will be used in subsequent experiments as a guide for constraining helicopter pop-up times to reduce AHT vulnerability.
