Abstract:

The objectives of this study were to analyze the system requirements and establish criteria for a relative motion simulation facility able to test and evaluate air-to-air or space mission scoring systems. Numbers present and forseeable future scoring systems were studied and their essential features abstracted. The relative motion characteristic of the two classes of intercept was analyzed and the significance of maneuver capability evaluated. Those aspects of an intercept observable by scores were summarized both quantitatively and qualitatively. Various techniques for mechanizing the intercept simulation were considered. The technique selected as most practical employed a projection system whose line-of-sight was rotated by a high-performance, DC servo motor, driven open-loop in a manner duplicating the real-time sweep of the missile to target displacement vector. Relative velocitymiss distance ratios up to 500 can be simulated exactly, and ratios up to 1000 simulated acceptably, using this technique. Hardware implementation will be simple and straightforward, and all major components are obtainable off-the-shelf. A preliminary design was developed for a facility capable of accommodating L- and S-band radar scorers and both active and passive optical scorers. The design allows extension to higher radar frequencies or to infrared by modular replacement of components, without major redesign.
