Global‐Scale Full‐Waveform Ambient Noise Inversion [PDF]
Journal of Geophysical Research: Solid Earth, 2020 AbstractWe present the first application of full‐waveform ambient noise inversion to observed correlation functions that jointly constrains 3‐D Earth structure and heterogeneous noise sources. For this, we model and interpret ambient noise correlations as recordings of correlation wavefields, which completely eliminates the limiting assumptions of ...

Chirp Signals and Noisy Waveforms for Solid-State Surveillance Radars
Aerospace, 2017 Since the advent of “pulse compression” radar, the “chirp” signal (Linear Frequency Modulation, LFM) has been one of the most widely used radar waveforms.
