AbstractThe near-field effect of extended target, i.e. the illuminated ground area of an active microwave sensor, is dscussed. It is shown by both analysis and numerical examples that all measurements are taken in the near-field and the value of normalized backscattering coeffcients are varytng periodically even for a uniformly dstributed scattenng characteristics target whde the platform altitude is increasmg. In order to compensate t h ~ s variation, a practical platform relocation techtllque is proposed
