Trading spectral efficiency for system latency in true-random noise radar network through template-replay diversity

The Air Force Institute of Technology (AFIT) has developed an experimental multistatic ultrawideband noise radar network (NoNET) to produce highly accurate, highly resolved imagery of a target scene while maintaining a featureless waveform for efficient spectrum utilization. In this work we present the results of an experimental study to assess the effectiveness of a template replay strategy to mitigate the effects of network latency in the radar network while preserving the Low Probability of Intercept (LPI) nature of the random noise (RN) waveform. Based on laboratory prototype measurements and a MATLAB model of two representative play-back schemes we demonstrate up to a 75% increase in processing efficiency while maintaining the ability to operate in a frequency contested environment.
