Abstract:

Results of HumRRO research to evaluate the problem of the effectiveness of tracer observation as a fire control technique for gun-type air defense weapons are reported. It was found that the machine dynamics of weapon systems are not compatible with the type of dynamics displayed by aircraft in a tactical situation. Also, several illusions are associated with tracer observations, and further, a gunner has difficulty in localizing a tracer with respect to the target because of limitations of stereoscopic vision and time delays associated with the feedback information provided by tracers. A need was indicated for controlled firing tests to evaluate the usefulness of tracer fire control for various combinations of aircraft dynamics, weapon dynamics, and tracer firing frequency. Author
