Design & implementation of activity detection based configurable Receiver architecture for EW application

This paper describe the design and implementation of two stage activity detection module to configure the Receiver architecture for meeting wideband, high sensitivity & 100% Probability of Intercept (POI) requirements for Electronic Warfare (EW) receiver covering 0.5-18 GHz. The Narrowband band receiver offers a high sensitivity but suffers from low POI as the instantaneous processing bandwidth is fraction of input bandwidth covered by receiver front end. The activity detection technique in this regards offers the wide open functionality in terms of frequency when used in conjunction with narrow band receiver. The design and implementation approach, advantages and limitations of this technique are mentioned in this paper.
