Abstract
The primary objective of the research was to develop procedures for optimizing the design of digital filter/comparator units for specific applications as for example, intrusion alarm systems. The study considered the various digital filtering operations and their performance in terms of target detectability and false alarm rate. The objective was to maximize the probability of detection and, at the same time, minimize the rate of false alarms. Since the operating conditions in a normal environment are not easily defined, reasonable assumptions were made on the nature of the target signals on the noise especially with respect to their time variations. As a second objective to the research, a model of an infrared intrusion alarm was designed and implemented. The performance characteristics of the model were evaluated in the final phase of the work.
