MEO SAR: System Concepts and Analysis

Existing microwave remote sensing instruments used for Earth observation face a clear tradeoff between spatial resolution and revisit times at global scales. The typical imaging capabilities of current systems range from daily observations at kilometer-scale resolutions provided by scatterometers to meter-scale resolutions at lower temporal...

3D NAND memories: A low cost space radiation monitor?

The thesis investigates the possible space application of a commercial 3D NAND memory as a radiation monitor. Literature has indicated that both traditional 2D and 3D flash memories are sensitive to ionizing radiation. Where the track of particle could be seen passing through the 3D architecture. A flash memory cell stores data with a collection...
