Abstract
A simulation device is provided for testing autotrack antennas. The device includes a mode coupler and transmit horn which are identical to the mode coupler and transmit horn of the antenna to be tested. The mode coupler has a plurality of waveguide input ports for transmitting voltage signals which are complex conjugates of signals occurring under receiving conditions. The device then generates a signal that simulates the far-field, plane-wave testing environment and applies this signal to an antenna to be tested.
