Abstract
Unstable narrowband signals in a background of noise are detected. Aside m the condition that the center frequency changes slowly, nothing is known about the signal dynamics or the signal and noise power levels. The incoming signal is translated into a waveform that emphasizes the correlated components regardless of their instantaneous carrier frequencies. This invariance suppresses consideration of the wandering aspect of the signal and permits a test for the presence of any narrowband energy.
