Abstract
The back scattering from a planar slot-array antenna is studied by the moment method and the technique of singularity elimination of the field integral. The scattering field from the conducting plane is computed by physical optics. Theoretical results of radar cross section (RCS) are compared with the measured ones
and good agreement is achieved. It is shown from this investigation that the scattering field contribution from the conducting plane is much greater than that from the slots.
