To study the electromagnetic scattering characteristics of the TX-1 microsatellite, an electromagnetic calculation model with a stealthy shape is established. The physical optics (PO) is used to numerically calculate the radar cross section (RCS) under different conditions to verify PO accuracy through comparing with anechoic chamber experimental results. This serves as a foundation for the development of the satellite RCS incidence angle, polarization, frequency, electric size response characteristics and full attitude angle spatial RCS response characteristics. Finally, the configuration is optimized to a symmetric pointed cone configuration referring to the TX-1's stealthy design. By increasing the quantity of sharp cone edges to optimize the configuration, the olive-shaped satellite with a lower RCS configuration is obtained. The TX-1's stealthy trait can effectively dispel the monostatic radar threat. The spatial RCS average value in the best stealth attitude is 4.89 dBsm less than that in the non-stealth attitude. Under S-band (3 GHz), the RCS average value and RCS amplitude of the olive-shaped satellite are 4.77 dBsm and 31.66 dBsm lower than those of TX-1. Under X-band (10 GHz), the RCS average value and RCS amplitude of the olive-shaped satellite are 3.65 dBsm and 43.97 dBsm less than those of TX-1.
