A brief theoretical methodology of Doppler shift LFM signal and the filtering technique is reviewed. Numerical Simulation and Experimental results are reported. Suppression of 8dB in Integrated Side Lobe Ratio (ISLR) is observed for a signal with 20dB SNR.

Simulation results are reported for Gaussian random noise cases as well as for a case utilizing Barker code of length 13.

She has a diverse portfolio of training and experience with program evaluation and research in education and healthcare, most recently as an evaluator for the Provost's Office at the University of Texas at El Paso and the Director of Evaluation for a 70 million-dollar National Institutes of Health funded center based at the University of Washington. She has experience assessing student learning and other outcomes for K-12 and higher education populations, including both two and four-year college environments all over the country, and ensuring programs have strong evaluation plans and the necessary data for evidence based decision-making.
