1. A method of calibrating an antenna array and signal processing system for receiving a frequency hopping communication signal comprising the steps of:

  • obtaining a frequency hopping sequence of the communication signal;

    receiving the communication signal;

    injecting a calibration signal at each of at least two frequencies of the frequency hopping sequence of the communication signal in response to receipt of said communication signal;

    determining calibration coefficients C1 and C2 for said at least two frequencies; and

    , applying C1 and C2 to a received signal.
