PROBLEM TO BE SOLVED: To provide systems and methods for creating a narrow vertical pathway of detection that permits enforcement of a fixed "exclusion zone" that is narrow and does not widen with range.SOLUTION: In some examples, systems and methods are configured to create a narrow vertical pathway of detection that permits enforcement of a fixed "exclusion zone" that is narrow and does not widen with range. An exemplary system located on an airframe includes at least two vertically separated antennas that receive radar reflection signals, a processor, and an output device. The processor receives the radar reflection signals received by the antennas, determines vertical positions of any obstacles identified in the radar reflection signals, and determines if the obstacles are within a predefined alert zone. The output device can output an alert if any obstacle is within the alert zone. The predefined alert zone is related to a protruding portion of the airframe. |
