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. WebRCS = 14,000 m2 at 10 GHz or 140 m2 1 GHz Sphere RCS = 1 m2 Independent of Frquency ... 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.
