ABSTRACT:
An antenna cosite analysis system with: interactive displays for i) designing an antenna tower for placement of one or more antennas on the tower, ii) designing wireless communication circuits, and iii) relating the antennas on the tower to the wireless communication circuits; and an RF analysis system for analyzing interference between the wireless communication circuits. A process for determining intermodulation interference between transmitters and one or more receivers includes the steps of: determining a minimum susceptibility of the receivers; determining a highest order intermodulation product generated as a result of interference between the victim transmitter and each other transmitter with a power level sufficient to exceed the minimum susceptibility of the one or more receivers at the victim transmitter; and determining the intermodulation products generated as a result of interference between the victim transmitter and the other transmitters, the intermodulation products being determined up to the highest order intermodulation product of a minimum leakage transmitter-victim transmitter pair. Also disclosed is a process for determining intermodulation interference in a receiver, an apparatus for determining intermodulation interference in transmitter, and an apparatus for determining intermodulation interference in a receiver.
