A new method for estimating the correlation of seismic waveforms based on the NTFT

W Cheng, L Liu, G Wang - Geophysical Journal International, 2021 - academic.oup.com
We propose a new correlation function called the similarity coefficient (SC) based on the
normal time–frequency transform (NTFT) to evaluate the similarity between two non …

Stellar angle-aided pulse phase estimation and its navigation application

Y Wang, Y Wang, W Zheng, M Song, G Li - Aerospace, 2021 - mdpi.com
X-ray pulsar-based navigation (XNAV) is a promising autonomous navigation method, and
the pulse phase is the basic measurement of XNAV. However, the current methods for …

Real-time and accurate pulsar time-of-arrival estimation using GA-optimized EMD-CS

L Liu, J Liu, X Ning, Z Kang - Optik, 2021 - Elsevier
For the estimation methods of the pulsar TOA (time-of-arrival) based on CS (compressed
