The stereo RCS of ship target is a main parameter in electronic warfare weapon efficacy test. Because of the difference of radar waves' incident angles, RCS of target exist different. This paper presents a RCS difference analysis method of feature selective validation, based on the character of ship target RCS in outfield and data analysis of ship RCS electromagnetic simulation. By analyzing the global difference quantity of RCS from different incident angles, the stereo RCS incident angles interval of ship target between outfield measurements is obtained. This method provides the basis for airborne platform RCS measurement scheme design, and advance the cost-effectiveness of outfield measurement. At last, this method has a certain guiding significance to the target providing analysis in new high-trajectory missile weapon system trial.
Key words: feature selective validation method; RCS; measurement scheme
