Abstract: Based on the lumped element models(LEM) analysis method for conducted interference which induced by space electrostatic discharges(SESD), this paper proves the equivalent circuit model for SESD source, and the modeling method for spacecraft structure and cables LEM, are proposed and the conducted interference coupling between SESD and the flat antenna system of a real satellite are analyzed. The results indicate that the LEM analysis method of SESD conducted interference is a useful tool for SESD protecting and evaluating in spacecraft engineering.
