Evaluation of Radar Cross Section of Trihedral Corner Reflectors Based on Improved GO/AP Method
Pages: 185-190
Year: Issue:  2
Journal: Radar Science and Technology

Abstract: The trihedral corner reflector is an important kind of passive countermeasure equipment,so it is quite significant to evaluate its radar cross section (RCS) efficiently and accurately.Taking the square trihedral corner reflector as an example,the general process of RCS estimation using GO/AP method is deduced,and the GO/AP method at boundary angles of incidence is improved.Then the RCS of square corner reflector and circular corner reflector are estimated by the improved GO/AP method.Comparison with FEKO simulation results as well as empirical formula of maximum value shows the validity and adaptability of the improved GO/AP method.Also,a fast RCS estimation method for all kinds of trihedral corner reflectors is proposed by combining the GO/AP method with the SolidWorks software.
