SPEARS, (System Performance Evaluation and Requirements Simulation): An AAW Performance Simulation.

This report is the documentation for a large-scale anti-air-warfare-oriented computer simulation model designated SPEARS System Performance Evaluation and Requirements Simulation. The model is, to the greatest extent practicable, machine and installation independent. The number of defensive and offensive units it can handle is limited only by available core storage. There are numerous applications for the model. Task force runs may be used to establish the relative effectiveness of the defense when changes are introduced in ship configurations alternate radars or weapon systems or in ship dispositions. Similarly the effects of changes in enemy attack tactics raid size, weapon types, flight profiles, jamming levels, or target selection are assessable. On a smaller scale, single-ship runs will allow the direct measurement of detection or firepower capabilities of an individual unit as changes are made in either the ship configuration or in the raid composition. The Track Data Handling System TDHS variant of the model offers a unique capability to examine the effects of increasing numbers of targets on the capabilities of operators to maintain accurate tracks and still be prepared to rapidly detect newcomers.
