← ScienceWhich risk increases when a high-power microwave beam disrupts a satellite's CMOS sensors?
A)Single event upset vulnerability✓
B)Increased data bus capacitance
C)Localized component melting
D)Antenna impedance mismatching
💡 Explanation
A single microwave pulse can cause single event upset (SEU) because electromagnetic induction creates spurious currents within the sensor. This exceeds threshold trigger levels therefore random bit flips occur rather than thermal damage or capacitance shifts under nominal operation.
