Instantaneous Bandwidth Expansion Using Software Defined Radios
Abstract
The Stimulated Unintended Radiated Emissions (SURE) process has proven capable of classifying a device (e.g. a loaded antenna) as either operational or defective. Currently, the SURE process utilizes a specialized noise radar which is bulky, expensive and not easily supported. With current technology advancements, Software Defined Radios (SDRs) have become more compact, more readily available and significantly cheaper. The research here examines whether multiple SDRs are able to replace the specialized Ultra-wideband noise radar used with the SURE process. The research specifically targets whether or not multiple SDR sub-band collections can be combined to form a wider band collection thereby achieving instantaneous bandwidth expansion. Simulations and hardware tests are conducted to verify the simulation results and prove the bandwidth expansion approach is successful. The results here demonstrate the ability to achieve instantaneous bandwidth expansion with the use of a cross-correlation approach to combine multiple sub-band collections into a single wider band collection without distortion or significant data loss.
