Integrated Ministack-InSAR Monitoring and Multi-Source-Factor-Informed CNN-LSTM Prediction of Reservoir-Bank Landslide Deformation: A Case Study of the Xiaolangdi Reservoir, China

Reservoir-bank landslides in canyon-type reservoirs commonly show slow creep and episodic acceleration driven by rainfall infiltration, groundwater fluctuation, reservoir regulation, and engineering disturbance. Sparse coherent targets and the high computational burden of long synthetic aperture radar image stacks limi...

Construction of Control Network for Multi-temporal LRO NAC Images Based on Matching of Lunar Impact Craters

Abstract. The Lunar South Pole (LSP) has extreme illumination, extensive shadows and weak surface texture, which greatly challenge high-precision mapping and render conventional image matching algorithms ineffective for control network construction. To solve this problem, this paper proposes a multi-temporal LRO NAC im...

Refinement of Asteroid Rotation Parameters via Stereo Intersection Angle Optimization and Masked Feature Matching

Abstract. Determining accurate asteroid rotation parameters is essential for establishing a body-fixed coordinate system during deep-space proximity operations. However, early mission phases often lack prior exterior orientation data. When combined with edge effects from the deep-space background, this deficiency leads...
