Radar cross section measurement by compact range method using 8-element small antenna array instead of one large antenna

RCS (radar cross section) measurement by the compact range method was performed using an 8-element small antenna array instead of one large antenna. The span of each antenna is 800 mm; 4 of the 8 antennas are used for transmission and the other 4 antennas are used for receiving. The transmission antennas and the receiving antennas are placed in cross relation with each other.
