Summary:
The simple RCS measurements are well-known as the near-field method to obtain the farfield RCS conversion [1], and the compact range method with the reflector [2] and the phasehologram range [3] for the scaled sized model target. The authors have investigated the scale model measurement and the Method of Moment (MoM) simulation with the Multi Level Fast Multi-pole Method (MLFMM) [4]. In this paper, the scale model measurement method in an anechoic chamber with 4.4m long and the physical optics (PO) simulation are presented. The simulation methods are compared for simulating the RCS of the scale model rocket. The measurement environment is examined in detail to reduce the mutual coupling between the transmitting and receiving antennas. The measured and simulated RCS results are compared with the theoretical values of the scale model rocket.
