Theory and practice of an Alltop waveform

Analog transmission of an Alltop digital sequence has been investigated. Three approaches to generate the continuous version of the Alltop sequence were studied — linear interpolation, Fourier transform (FT) expansion and direct over-sampling. The feasibility of the transmission using the three methods was investigated through simulations and waveform synthesis in an actual waveform-agile radar system. Applicability of sparse signal processing with generated Alltop waveforms has been demonstrated.
