High-Resolution Radar Waveforms Based on Randomized Latin Square Sequences
Abstract
This report summarizes the study of Sudoku puzzles as applied to radar applications. We examine Sudoku puzzles for frequency hopped sequences with comparison to the well researched Costas frequency codes. Utilizing the backtracking algorithm, numerous Sudoku puzzles varying in size are generated for analysis of their co-hit and cross-hit properties as compared to Latin Squares. We look at how Sudoku sequences compare to traditional waveforms such as linear frequency modulation and rectangular pulse. Furthermore, we investigate the use of Sudoku puzzles for antenna applications including array interleaving, array thinning, andrandom element spacing. Finally, radar simulations and comparisons are performed using the frequency coded Sudoku sequencesfor stationary and moving targets. It is concluded that Sudoku based sequences and antenna array configurations show significantpromise in architecting high-resolution radar waveforms and enhancing antenna beamforming capabilities
