The radar cross section (RCS) of a photoelectric turntable through software simulation.Based on the principle of high frequency locality of scattering,the RCS prediction of the target is completed.Simulate the RCS of the photoelectric turntable in the S,C and X bands,under 0～3 incident residual angle.Decompose the complex optoelectronic turntable,study the RCS characteristics of each part,and carry out stealth design of the optoelectronic turntable.A simulation analysis was performed on the turntable after the stealth design was completed.After the stealth design,the proportion of RCS with an average value greater than 0.5 m2 was approximately 18.18%.The stealth characteristics of the photoelectric turntable were significantly improved.
