测量雷达作用距离时通常对应于特定的配试目标。不同配试目标的雷达截面(RCS)会随着视角、工作波长、姿态等因素变化而变化。目标RCS的测量方法有多种，通过动态检飞得到的RCS应该是最可靠的。该文利用对某雷达外场检飞数据，对某民航机、某战斗机、某直升机、某小型教练机四种飞行目标在UHF波段的最大作用距离和RCS进行了估算分析。

Radar range generally has definite target. The RCS of different target will change with wavelength, flighting pose and such factors. The RCS got from flight should be most reliable. Based on the flighting data of one radar, the radar range and the radar cross section of one civil aeroplane, one battleplane, one helicopter, one small training plane are analyzed in this article.
