System and method for finding a direction of two or more secondary RF sources arrayed about a position of a primary RF source (X). The system includes an antenna system () coupled to a monopulse tracking system () for determining a position of a primary RF source relative to a boresight axis () of the antenna system. The system includes a monopulse direction finding system () coupled to the antenna system responsive to RF signals from two or more secondary RF sources (Y, Y) having at least one of a different frequency and a different polarization as compared to the primary RF source.

A broadband adaptively controlled polarization separation network. Two transmitted signals vertically and horizontally polarized are received as elleptically polarized signals. One of the two received elliptically polarized signals is automatically adjusted to make it linear and thereafter automatically adjusted to make it vertical. If the other signal does not have any vertical polarization on it then the two signals are easily separated and nothing else is needed. However, if there is any vertical polarization on the other signal this invention provides for separating the resulting crosstalk between the two signals. This is done automatically by the use of two sets of crosscouplers which couple a single line to the other line to complete the polarization decoupling operation.
