Analysis of the Optical Memory and Transducer Requirements for the OMFIC System Applied to Guided Projectiles.

摘要

The Optical Matched Filter Image Correlator (OMFIC) can identify targets and their number, and provide information about their bearing, positional coordinates, range interval, and velocity. Thus, it provides a new concept for the missile or projectile guidance application. The optical memory size and real time transducer update requirements are two of the most important aspects of the OMFIC system when used for guiding a projectile. An analysis of these factors shows that the memory bank requirements are manageable and within current technology capabilities. In order to cover the range from acquisition (1.5 km) to approximately 50 meters from impact only 397 memory positions are required for highly discriminating matched filters. The transducer update rate can be set at television frame rates for guidance to 50 meters from impact at approximately M sub f = 0.5. Other aspects of the OMFIC memory bank and transducer requirements for missile/projectile guidance are developed in the report.
