摘　　要：RCS动态测量可以获得真实环境中目标的RCS,是目标与环境特性研究的重要手段之一。针对舰船目标RCS动态测量中因目标姿态和位置不断变化造成RCS测试数据与目标测试角度无法直接对应的问题,提出了角度内均值和数据角度求取两种测试数据角度修正方法。两种方法将组合导航数据通过坐标系转换和角度计算获得测试角度的时间序列,与RCS测试数据时间序列综合处理,得到测试数据与角度之间的对应关系,支撑舰船目标RCS缩减、特征模拟等研究。通过试验验证了提出方法的有效性和正确性。RCS dynamic measurement can obtain the target RCS in the real environment, which is one of the important means to study the characteristics of the target and the environment. Aiming at the problem that the RCS measurement data cannot directly correspond to the target measurement angle in the dynamic measurement of ship target RCS because of the attitude and position of the target are constantly changing, two methods for correcting the angle of the measurement data are proposed in this paper. The two methods use coordinate system conversion and angle calculation to obtain the time series of the measurement angle, and comprehensively process the time series of the RCS measurement data to obtain the corresponding relationship between the measurement data and the angle, which supports ship target RCS reduction and feature simulation research. The effectiveness and correctness of the proposed methods are verified by experiments.
