1. A measurement device for measuring phase and power shifts in a simultaneous dual polarization radar system, comprising:

  • a. an access port configured to couple to said simultaneous dual polarization radar system near the antenna of said simultaneous dual polarization radar system;

    b. a quadrature mixer configured to mix a first signal from a first polarization and a second signal from a second polarization, said first signal and said second signal sampled through said access port; and

    c. a first power detector configured to measure the power level of said first signal.
