    transmitting radar signals from an airborne radar unit that reflect off of objects, said reflected radar signals being received by said radar unit;

    processing said received signals in real-time to compensate for a state vector of said aircraft relative to said landing area, comparing information of said received radar signals with a portion of said stored ground feature information; and

    detecting obstacles which are additional to said stored radar feature and map position information.
