1. A method of determining range information associated with a target, the method comprising:

  • receiving a near return signal reflected from a near target;

    receiving a far return signal reflected from a far target, at least a portion of the far return signal overlapping in time with the near return signal;

    generating a reference signal that corresponds to the far return signal;

    weighting at least part of either the far return signal or the reference signal to produce a weighted far return signal or a weighted reference signal, respectively; and

    performing pulse compression using the weighted far return signal or the weighted reference signal to determine range information associated with the far target that is at least partially free of interference from the near return signal.
