1. A method of using an airborne weather radar, the method comprising:

  • providing a first radar pulse at a first beam position during a radar scan and receiving a first return, the first radar pulse being a velocity sensing beam;

    providing a second radar pulse at a second beam position during the radar scan and receiving a second return, the second radar pulse overlaps and is not identical to the first radar pulse;

    providing a third radar pulse using a lower gain with a wider beam width at the first beam position during the radar scan and receiving a third radar return, the third radar pulse being a side lobe detection beam; and

    processing the first return, the second return and the third return and using data associated with the first return, the second return and the third return to identify and remove non-weather targets weather phenomena detection.
