Logarithmic Frequency Waveforms
A New Paradigm in Radar Signal Processing
Logarithmic Frequency Waveforms (LFWs) are a new class of Doppler estimation capable radar and communications waveforms, created by mapping the magnitudes, phases, and spacing of good digital codes onto a set of carriers defined over a logarithmically warped frequency axis. This mapping preserves the digital code’s autocorrelation mainlobe-to-sidelobe ratio when matched filtering is done over the warped frequency variable. The logarithm converts the multiplicative Doppler shift into an additive translation of the code’s autocorrelation, thus the location of the matched filter output is used to estimate the waveform’s Doppler shift. There are two major classes of Logarithmic Frequency Waveforms: Logarithmic Frequency Codes (LFCs) and Logarithmic Frequency Rulers (LFRs). LFCs utilize phased radar codes, such as Barker and Frank codes, while LFRs use Golomb rulers.
