Abstract The geodynamic processes that formed Earth’s earliest continents are intensely debated. Particularly, the transformation from ancient crustal nuclei into mature Archaean cratons is unclear, primarily owing to paucity of well-preserved Eoarchaean–Palaeoarchaean ‘protocrust’. Here, we report a newly identified Palaeoarchaean continental fragment—the Baishanhu nucleus—in northeastern North China Craton. U–Pb geochronology shows this nucleus preserves five major magmatic events during...
The target's threat prediction is an essential procedure for the situation analysis in aerial defense system. However, traditional methods mostly ignore effect of commander's emotion. They only predict a present from features itself, which leads to their poor ability complex situation. To targets, this paper proposes method its potential considering commander emotion (PTP-CE) that uses Bi-directional LSTM (BiLSTM) network and backpropagation neural (BP) optimized by sparrow search algorithm...
The debate on the role of vertical versus horizontal tectonism in Archean cratons is intimately linked to initiation plate tectonics. dome-and-keel architecture has been considered as a consequence tectonism. Although such structural pattern documented some Mesoarchean and older cratons, Kaapvaal Pilbara whether it also occurs Neoarchean poorly constrained. Determining kinematics, evolution, timing these structures crucial understanding how tectonic behavior operated during evolution early...
In the traditional X-ray pulsar Doppler velocimetry approach, a single only provides velocity information of spacecraft in line-of-sight (LOS) direction pulsar. Theoretically, we prove that error any can distort profile orbit around Jupiter. Moreover, using singular value decomposition (SVD), find observability velocities both maximal and middle directions is far better than minimal one. Based on theoretical analysis results, propose two-dimensional approach to provide more for spacecraft....
Abstract The measurement of the celestial Doppler difference velocimetry navigation is between solar spectrum and planetary spectrum. asynchronous solar/planetary spectral pairs in existing database lead to difficulty verification navigation. To solve this problem, we propose a VAE+CycleD2GAN-based generative method synchronous pairs, which fuse variational auto-encoder (VAE), cycle adversarial network (CycleGAN), dual discriminator nets (D2GAN). In CycleGAN, spectra are used as training set...

Deep space exploration, generally referring to the exploration activities targeting Moon and more distant extraterrestrial celestial bodies, stands as a critical indicator of nation’s comprehensive capabilities technological prowess [...]
Deep space exploration missions continue to become more ambitious, driving the need investigate autonomous navigation systems that are accurate and timely. The solar Doppler difference is a newly developed promising celestial method for use, particularly, in crucial capture period. In this paper, we present novel analyses three error sources from perspective of geometry, motivated with Mars deep example. geometry include area overlap rate direct reflected light sources, spread effects...

In celestial spectral velocimetry methods, when the solar spectra are stable, highly accurate velocity information of spacecraft can be derived from Doppler frequency shift. However, activity cause a shift in spectra, greatly affecting accuracy velocimetry. Due to limitations payload and computing resources, we propose compensation method that only uses single band images spectra. addition spectrometer used by traditional add one optical imaging sensor. We conduct grey correlation analysis...
