1. A method for transmitting signals from multiple antennas from a communications platform, the method comprising:

  • receiving, at a first receiving station, a first combined signal comprising a first signal transmitted by a first antenna and a second signal transmitted by a second antenna, wherein;

    the first signal and the second signal are transmitted at a single frequency, andthe first antenna and the second antenna are separated by a first distance;

    receiving, at a second receiving station, a second combined signal comprising the first signal transmitted by the first antenna and the second signal transmitted by the second antenna, wherein;

    the first receiving station and the second receiving station are separated by a second distance; and

    determining the first signal and the second signal based on the received first combined signal and the received second combined signal;

    wherein the second distance of separation between the first receiving station and the second receiving station is based on the first distance of separation between the first antenna and the second antenna such that an additive array factor is provided resulting in a peak on one of the first antenna and second antenna and a null on the other of the first antenna and second antenna, and wherein determining the first signal and the second signal is further based on the additive array factor.
