Combining Sensors with Airborne Telemetry Instrumentation to Make Range Measurements and Obtain Aerodynamics

摘要

Obtainning a projectile's free-flight motion profile and its aerodynamic coefficinets is typically accomplished at indoor test ranges using photographic techniques synchronized to timing stations Since these ranges are relatively short, many discrete tests are mecessary to compile a complete understanding of the projectile's behavior. When Time Space Position Information (TSPI) is requested over long-range flights, it has been gathered with expensive video, laser, and radar trackers. These can be inaccurate at times and are limited to locations where the range equipment is able to track the projectile's entire flight. With the ever-increasing sophistication of ordnance, such as smart and competent munitions that have multi-stage thrusting and maneuvering capability, it is becoming increasingly difficult to make the necessary measurements using current measurement techniques.
