High-Resolution Radar Waveforms Based on Randomized Latin Square Sequences
Abstract
Investigate in detail the high-resolution properties of frequency-hopped radar waveform sequences derived from Latin squares and specifically explore the advantages and disadvantages of special sequences for applications. Investigate the auto-ambiguity and cross-ambiguity functions of 9x9 Latin square sequences. Derive the average auto-ambiguity functions and compute the peak side-lobe level statistics of each sequence realization. Explore the ambiguity functions for higher order sequences. Analyze the relationship between the order of the sequence and such metrics as delay resolution, Doppler resolution, peak and average side-lobe levels, and cross interference levels. Investigate the Doppler tolerance of these sequences as a function of sequence order. Develop MIMO radar configurations based on Latin square hopping sequences and analyze their orthogonality. Determine if the additional orthogonality from totally orthogonal arrays can be exploited to construct spectrally efficient waveforms so that radar systems can operate in close proximity.
