Method and apparatus for processing an under-sampled chirped sinusoidal waveform using a complex-heterodyne

摘要

A method of processing data acquired by under-sampling a chirped, sinusoidal waveform comprises complex-heterodyning the under-sampled data with a chirped signal having characteristics similar to the sinusoidal waveform to generate a demodulated signal and analyzing the demodulated signal to determine characteristics of the sinusoidal waveform.
