In near field scattering measurement, for acquiring the radar cross section of targets which have multiple interactions, nearfield to far field transformation require the full bistatic near field measurements. However, with traditional bistatic nearfield scattering measurement, it is assumed that the number of observations in farfield is equal to the number of antennas on the scanning plane, which would multiply the time cost and make it hard to be applied in practice. Therefore, a method is proposed to reduce the testing angle region and combine a system consisting of one transmitting antenna, multiple receiving antennas and the rotation of platform, to verify its effectiveness. Finally, the results for testing a dihedral angle in the microwave anechoic chamber have been given to prove its correctness and feasibility.
