Abstract
In this manuscript, we analyze chirps in noise using the evolutionary maximum entropy spectral estimator (EMES). First, brief descriptions of evolutionary spectrum and its estimators, the evolutionary periodogram (EP), the smoothed evolutionary periodogram (SEP) and the EMES are given. Then, chirps in noise are analyzed with the EMES. It is shown that the EMES parameters are weighted functions of frequency components around the time of analysis. Later, the relation between bandwidth, SNR and number of basis functions is given for the case of a single pure sinusoid.
