Abstract在推导散射计 对校准公式的基础上,远区条件对于雷达散射计绝对校准的意义,通过引入有效雷达散射截面的概念,将入射波前球面弯曲和波束限制引起照射不均匀以及接收天线增益的变化等效为目标雷达散射截面的变化,通过修正使近,远场的绝对校公式得以统一,给出相应的绝对校准方法.
Other AbstractIn this paper,procedu re of the ab solute calib ration for ground based scat terometer is presen ted. Effect s of the far f ield criterion for the calib rat ion is analyzed. The concept of effective radar cross section (ERCS) is in troduced to unify the calib ration formula for near field region and far f ield region measu rement.Ap ract ical calib rat ion method is p ropo sed.Some calib rat ion resu lt s show the validity of the given method.
