Pulsar identification method based on adaptive grey wolf optimization algorithm in X-ray pulsar-based navigations
H Zhao, J Jin, B Shan, Y Jiang, Y Shen - Advances in Space Research, 2022 - Elsevier
Fast and accurate identification of pulsar signals is important for X-ray pulsar-based
navigation (XNAV). Traditional pulsar signal detection technology based on FFT search and
epoch folding (EF) requires a very long time to obtain an appropriate signal-to-noise ratio
(SNR) gain, especially for weak pulsar signals with low photon fluxes. This paper proposes
an adaptive stochastic resonance (SR) method based on the grey wolf optimizer (GWO)
algorithm for fast pulsar identification. The GWO algorithm can optimize the SR parameters …
