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.
