Systems and methods for providing improved situational awareness for an aircraft while taxiing. An exemplary method generates reflectivity data based on an associated emission at a transceiver located on an aircraft. At a processor, targets are determined if a portion of the generated reflectivity data is greater than a predefined threshold. Then, the analyzed targets are determined as to whether they are within a dynamically defined three-dimensional envelope. The envelope is based on wingtip light module speed and trajectory. On a display device, an indication of the nearest target is presented at the associated range to the nearest target.
