AME: A Cross-Scale Constellation of CubeSats to Explore Magnetic Reconnection in the Solar–Terrestrial Relation

Frontiers in Physics, 2020
A major subset of solar–terrestrial relations, responsible, in particular, for the driver of space weather phenomena, is the interaction between the Earth's magnetosphere and the solar wind.

A New Remote Sensing Change Detection Data Augmentation Method Based on Mosaic Simulation and Haze Image Simulation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The quality of optical remote sensing images is largely affected by clouds and haze. In addition, the mosaicking image of multiple remote sensing images, due to objective factors such as acquiring time or climate conditions, will lead to large spectral ...

Evolution of Spaceborne SAR Missions in Earth Orbit

Remote Sensing
A truly operational SAR was first flown in space in 1978 on board the Seasat satellite. Since then, its utilization first expanded to Canada, Europe and Japan, and then to countries with emerging space industries later on. Many technological developments
