1. A method in an RF system comprising first and second RF receivers separated by a predetermined distance, d, and an RF transmitter, the method comprising the steps of:

  • [1] in the first and second receivers, synchronizing the first and second receivers to a predetermined time base;

    [2] in the transmitter, transmitting an RF signal having a predetermined carrier wavelength, A;

    [3] in the first receiver, receiving the transmitted signal and developing a first phase value as a function of the complex baseband impulse response of said received signal;

    [4] in the second receiver, receiving the transmitted signal and developing a second phase value as a function of the complex baseband impulse response of said received signal;

    [5] developing a phase difference value, a, as a function of the first and second phase values; and

    [6] developing an angle of arrival, θ

    , of the transmitted signal relative to the first receiver according to the following;
