Abstract :
During the reentering process, the RCS of the reentry capsule of Shenzhou spacecraft changed violently because of plasma sheath and wake. The change in turn affected the ground-based telemetry radar. Based on the actual measured data of C-band radar, this article analyzed the mechanism of the sudden increase and reduction of RCS of the reentry capsule and demonstrated the theory in WKB method.
