A ground crew collision-avoidance system includes a plurality of radar sensor modules that each emit a radar signal, receives at a radar detector radar return signals corresponding to reflections of the emitted signal from a ground object, and transmits radar information associated with the received radar signal reflections reflected from the ground object, wherein each of the plurality of radar sensor modules are uniquely located on a surface of an aircraft that is at risk for collision with a ground object while the aircraft is being towed; a gateway unit that receives the radar information transmitted from the radar sensor module and transmits information associated with the received radar information; and a ground crew alert indicator that receives the information transmitted by the gateway unit and that presents a graphical alert icon on a display. The display indicates a likelihood of collision between the aircraft and the ground object.
