|
 | Two simulator experiments, differing only in field of view (FOV), were conducted to investigate air-to-ground target acquisition with color and black and white television. A television camera obliquely viewed a terrain model from a simulated altitude of 4,000 feet with two FOVs: 4.5 and 3.25 degrees. Subjects searched for green, olive, brown, and earth-colored tanks and trucks as the camera 'flew' over the terrain. It was found that (1) color ... |

|
| A laboratory experiment was conducted on a terrain model to assess the effect of a hovering flare on target acquisition performance. One group of subjects was asked to search for targets of opportunity by the light of two hovering flares. Another group searched with two normally descending flares. The hovering flare group found 59% of the targets as compared to 52% by the descending flare group. Although this difference is ... |

|
 | This report develops a framework which structures the variety of modeling approaches that might be taken in quantifying visual target acquisition. Significant omissions in current modeling efforts are identified. Past modeling approaches are described, including those emphasizing cognitive and subjective approaches. It is concluded that mathematical modeling is so dependent upon (1) the objectives of the user, (2) the class of situation being modeled, and (3) the methodological orientation of ... |

James E. Coursey; ARMAMENT DEVELOPMENT AND TEST CENTER EGLIN AFB FL
|
| This report describes a test conducted to determine the feasibility of using a photographic/microdensitometer technique to determine target contrast at event times for combat air support and target detection/acquisition/identification tests. Data obtained from this test, with related problems and limitations, are presented and analyzed. The data consist primarily of target luminances and contrasts as functions of atmospheric attenuation, slant ranges to the targets, elevation angles, weather parameters, and camera/lens combinations. ... |

|
| An analysis was performed to determine the effect of the atmosphere on target-background contrast under flare illumination. It was found that atmospheric effects contributed significantly to the reduction of contrast between target and background. (Author) |

|
| A dog-leg turn may be used to unmask the target and obtain post-launch tracking data for the computation of control orders. The timing and direction of the turn, and the length of the dog leg, are examined to determine the sensitivity of the acquisition probability to these variables in the corrected-intercept mode. The length of the dog leg is computed in a way that assures that unmasking will occur and ... |

| Studies in Manual Target Designation: Isometric Controls, |

| Authors:
Thomas C. Way; BOEING CO SEATTLE WA
|
| This document reports a series of tests in which operators used one of three force (isometric) controls to position a ring cursor over a dot target presented on a 17-inch 1000-line television monitor. Optimal parameters were first established for each of the three controls: a hand-operated grip, a finger-operated stick, and a thumb-operated disk control. A final test compared the three controls with respect to designation error and the finger ... |

|
| The primary purpose of the Practice Guided Weapon (PGW) is to train pilots on target acquisition and launch sequence procedures. In addition, the PGW, because of its similarity to the Guided Weapon Mk 1 Mod 0, is an ideal training device for aircraft handling, loading and maintenance crews. On a typical training flight using the PGW, the pilot is given a flight plan and targets are designated. The pilot makes ... |

|
| The report describes a series of tests designed to investigate resolution and target recognition performance under conditions of direct viewing and TV mediated viewing of appropriate test stimuli. The long range objective of the program is to determine the television display simulation requirements that will enable, for training purposes, visual target acquisition performance comparable to that obtained in the real world. The study utilized resolution bar charts and simple target ... |

|
| As part of a USAECOM program to study the feasibility of applying high resolution techniques to combat surveillance radars, selected electronic switching devices capable of generating nanosecond pulses were investigated and certain operational characteristics determined. These devices were: hydrogen thyratrons, switching transistors, avalanche transistors, and snap-off diodes. Pulses were generated down to one nanosecond at pulse repetition frequencies up to 50 megacycles. Hydrogen thyratrons and avalanche transistors were used in ... |
