1. Qualls, Isaiah Christopher. OPTIMIZATION OF DUAL-USE RADARCOM SIGNALS AND AN ANALYSIS OF INTERCEPTOR PENALIZATION.

Degree: MS, Computational Science and Engineering, 2019, Miami University

This thesis proposes a novel "search and sort" algorithm for an Ultra-Wideband Orthogonal Frequency Division Multiplexed (UWB-OFDM) signal. This algorithm is used to optimize the Peak to Average Power Ratio (PAPR) and Proportional Sidelobe Ratio (PSLR) of signals generated via a Weibull Random Process being used to determine the sub-channel weights of the signal. Two methods are compared using this algorithm, PSLR First Method and PAPR First Method. Additionally, analysis is provided pertaining to covert communication using this random modulated scheme, to provide evidence of penalization of an intercepting platform, using a Maximum Likelihood Estimator to determine the shape key of the transmitted signals.Results from the 2-parameter optimization showed that PAPR is independent of which method is chosen as it showed an improvement of about 5.5 dB when compared with the average PAPR of all signals sampled; however, the PSLR results show that the PSLR First Method has an improvement of about 5 dB whereas the PAPR First Method has an improvement of about 20 dB over the average.The interceptor penalization shows that, in a simulation of 10,000 transmissions, the number of transmissions required to reach a selected Data Intercept Fidelity (DIF) increases as the DIF increases. Furthermore, the number of transmissions needed to reach higher DIF thresholds is exponentially higher. Finally, discussion of the experimental setup and results are covered using a Software Defined Radar System.
