摘　　要：介绍了龙伯透镜反射器用于雷达回波反射的诸多优点及其主要性能指标,分析了龙伯透镜反射器RCS测试过程中产生角度误差的原因,并指出了该误差引起的零点偏移会影响其性能指标的评估分析。针对这一问题,提出了最大RCS值法和响应区间中心法,阐述了两种算法的工作原理及实现流程,应用算法对实测RCS数据进行预处理,评估了所测样机的主要性能,验证和比较了算法的有效性及差异性。As a kind of radar echoes reflector, the advantages and main peformances of Luneberg lens reflector are introduced. And then why the angle errors is analyzed, which result in the offset of zero point to enfluence the statistical analysis of the reflectors＇ performances, exists in the measuring process. For solving the above problem, the maximal RCS method and the response area＇s center method are advanced, and the op- eration principle and implementation flow are expounded. Finally, for validation and comparision, the algorithms are applied in pre-processing RCS data of Luneberg lens reflectors and the result is interpreted.
