MEASUREMENT OF JAMMING EFFECTIVENESS BY CROSS CORRELATION TECHNIQUES(C)

Abstract

A method and apparatus is disclosed for automatically and repeatably measng the effectiveness of jamming applied against a communications link. The method is machine performed, free of the need of listener personnel, and the recording and scoring tasks required in conventional methods. Using a ratio of auto and cross-correlation functions, a number is produced (CCI Index) which is the desired measure of jamming effectiveness. The CCI Index is a standardized value which indicates jamming effectiveness in any type communications link regardless of equipment or type of modulation in use. The Index, rapidly obtainable, can be used to pinpoint which jamming technique might be most advantageously employed, and by precisely how many db it would be superior.
