Field of View Analysis of SeaWinds Reflector Antenna

Antennas are often mounted among many other instruments on the spacecraft platform. The electromagnetic interference (EMI) and compatibility (EMC) issues are of great concern to the antenna and spacecraft system design engineers. Considering the rotating reflector antenna of the NASA SeaWinds Scatterometer on the Japanes ADEOS II spacecraft, it is desirable to determine the antenna's field of view (FOV) performance. In other words, how far should the other boxes be kept away from the reflector antenna to minimize the blockage/diffraction effects on the antenna's performance requirements.
