Abstract :
The near field system can be used for measuring the performance of antennas and it can also be used for RCS (Radar Cross Section) measurement. The far field patterns for both antenna and RCS can be generated by the transformation of the measured near field data. In this paper the concept of transformation is applied for obtaining the far field RCS of a radar target from the near field measurement data. The processing technique is used to generate the far field RCS pattern. The results of far field RCS by this proposed technique agree quite well with that obtained by direct far field measurement
