Electromagnetically related performance of large weapon platform, including radiation performance, compatibility (antenna placement, coupling between antenna arrays at the same frequency /different frequencies), detectability and protection, is a complicated and difficult problem for simulation. The difficulty comes from (i) large/very large electrical size (100-1000 wavelengths) (ii) Complex structure and material (e.g. cavities, absorbing materials, etc.) (iii) coupling between different antennas of different frequencies (iv) conformal structure on curved surface. After long-term research, EastWave has developed targeted solutions for antenna-platform coupling, antenna-antenna coupling, antenna placement and conformal antenna.
