Detection Methods for Stealth Radio Signals: A Literature Survey

摘要

In military radio communication systems, a central feature is often the abilityto avoid discovery by some hostile interceptor. Therefore, when designing such a stealth radio system, it is naturally important to have knowledge of the different existing signal detection methods, i.e., the threats to a stealth radio system. This report is a literature survey of some of the most interesting methods of detecting different types of digitally modulated radio communication signals. The methods covered are wide-band radiometer detection, optimum detection and cyclic-feature detection. Comparisons between the different methods are also performed.
