Abstract

As part of research conducted on the design of an efficient clutter covariance processor for DARPA's knowledge aided sensor signal processing expert reasoning (KASSPER) program a time-dual for information theory was discovered and named latency theory, this theory is discussed in this first of a multi-paper series. While information theory addresses the design of communication systems, latency theory does the same for recognition systems. Recognition system is the name given to the time dual of a communication system. A recognition system uses prior-knowledge about a signal-processor's input to enable the sensing of its output by a processing-time limited sensor when the fastest possible signal-processor replacement cannot achieve this task. A processor-coder is the time dual of a source coder. While a source coder replaces a signal-source to yield a smaller sourced-space in binary digits (bits) units a processor coder replaces a signal-processor to yield a smaller processing-time in binary operators (bors) units. A sensor coder is the time dual of a channel coder. While a channel coder identifies the necessary overhead-knowledge for accurate communications a sensor coder identifies the necessary prior-knowledge for accurate recognitions. In the second of this multipaper series latency theory is successfully illustrated with real-world knowledge aided radar.
