Abstract : The objective of the Interactive Surveillance Avoidance System (ISAS) development effort were to: 1) demonstrate a process for generating near-optimal ship transit routes that avoid surveillance by enemy sensors located in space, in the air, on the surface, or undersea; and 2) demonstrate a friendly computer environment in which the user can easily provide necessary information to the system and in which the system displays information in an easily comprehended form to the user. The analytical procedure for generating an optimal path was demonstrated, as was a man-machine interface that fosters interaction between the transit planner and the system. This project was to demonstrate the feasibility of the concept and to estimate the computer system requirements for introducing the capability into the fleet environment. ISAS could be useful to the fleet in planning transits before leaving port, and in re-planning the remainder of a transit when new information becomes available about enemy sensors, weather forecasts, or changes in final destination points, rendezvous points and times. ISAS consists of both analytical and man-machine interface software implemented on a variety of hardware items. The hardware consists of a VAX 11/750 minicomputer, an Ann Arbor Ambassador CRT terminal, a color graphics monitor, a CROMEMCO microprocessor that serves as interface between the VAX and the graphics monitor, and a line printer. The software is written in a highly modular fashion.
