RCStgt (dBsm) = RCSstd (dB) - RCStgt (dB) The data is expressed in dBsm, or decibels referenced to one square meter. Radar cross section in square meters can be converted to dBsm by the following equation. Web由于各向异性介质特殊的电磁特性,不仅能吸收雷达发射波,还能通过控制介质光轴使散射波能量集中于雷达非观测方向,进一步提升目标隐身性能[7-8],因此在目标雷达特性研究领域,各向异性介质涂覆目标电磁散射建模备受关注[9-10]。 WebMar 1, 2001 · RCS (dBsm) = 10.0 * log10(linear RCS) Therefore, it is incorrect to state that an object has a single definite value of RCS, since this value is dependent on many different variables. Average RCS over some angular sweep is generally specified for objects just as aircraft and missiles, however, RCS can vary by as much as 30-40 dB as angle changes. cyclone 10 lp family
