NASA ISRO Synthetic Aperture RADAR (NISAR) Spacecraft Electric Field Studies

The objective of this analysis is to derive radiation susceptibility levels for subsystems in the NASA ISRO Synthetic Aperture RADAR (NISAR) Spacecraft at Sband SAR payload frequency. This involves finding electromagnetic field distribution at various subsystem locations. The analysis was carried using Computer Simulation Technology (CST) microwave studio software. In Microwave studio Time Domain Solver with Finite Integration Technique (FIT) is used to find out the Electric field distribution at various panels of the spacecraft.
