An aircraft collision avoidance system including (a) at least one separation monitoring device connectable to at least a portion of an aircraft and/or vehicle, the separation monitoring device comprising (1) at least one transmitter, (2) at least one receiver, and (3) an image sensor, and (b) a master unit.

Systems and methods for aiding in pilot awareness of obstacles relative to aircraft features. An exemplary processor receives sensor information from one or more sensors mounted in an aircraft feature (e.g. light modules), determines if at least one obstacle is located within a predefined field of view based on the received sensor or database information and generates an image. The image includes an ownship icon having at least one feature representing wingtips of the aircraft and at least one indicator associated with the determined at least one obstacle. A display device presents the generated image. The display device presents a tip of a first sense coverage area adjacent to one wingtip feature associated with the port wing and a tip of the second sense coverage area adjacent to one wingtip feature associated with the starboard wing. The indicator is presented within at least one of the coverage areas.

To provide a foreign-object system which uses a plurality of radars, and which can detect a foreign object that is present on a runway or the like and which can suppress interference between radars. A foreign-object detection system including a first radar 11, a second radar 21 connected to the first radar via a network 33, and a signal source 31 for transmitting a synchronization signal to the first radar and the second radar via the network, said foreign-object detection system wherein interference generated due to a radar signal outputted from the second radar being reflected by a reflective body and inputted to the first radar is prevented by controlling a delay time that corresponds to |.sub.1i.sub.2j|, where .sub.1i is the time taken for the synchronization signal to be transmitted from the signal source to the first radar, and .sub.2j is the time taken for the synchronization signal to be transmitted from the signal source to the second radar.

A ground obstacle collision-avoidance system includes a plurality of radar sensor modules that each receive at a radar detector radar return signals corresponding to reflections of the emitted signal from a ground obstacle, and transmits radar information associated with the received radar signal reflections reflected from the ground obstacle, 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 obstacle if the aircraft is moving; a gateway unit that receives the radar information transmitted from the radar sensor module and transmits information associated with the received radar information; a processing system configured to determine a distance from the installation aircraft to a detected ground object detected; and a display configured to present a plan view indicating an aircraft icon and a graphical ground obstacle icon that is associated with the detected ground obstacle.

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.

A system and method is provided that displays graphical symbology that enables a pilot to rapidly discern (1) that a neighboring aircraft is a rotorcraft, and (2) whether the rotorcraft is hovering. The provided system and method enables a user to define hovering, by editing a position change (distance) within a predetermined time.
