A system including a radar system. The radar system may include a transmit antenna, a receive antenna, and a controller. The controller may be configured to: determine or obtain information indicative of at least one of a phase of flight or an environmental condition; determine or obtain information indicative of a mission associated with the determined phase of flight and/or environmental condition; and based at least on the determined mission and the determined phase of flight and/or the environmental condition, tune radar parameters of the radar system to values to fulfill the determined mission associated with the determined phase of flight and/or environmental condition. The radar system may be reprogrammable by tuning the radar parameters to operate over any of a collection of phases of flight, any of a collection of environmental conditions, and any of a collection of missions.

Methods, devices, and systems for false target detection for airport traffic control are described herein. One device includes a user interface, a memory, and a processor configured to execute executable instructions stored in the memory to receive one or more sensor reports from one or more sensors, aggregate data that corresponds to a particular target from the one or more sensor reports, determine the particular target is a false target responsive to only one of the sensor reports including data that corresponds to the particular target, and display the particular target as a false target on the user interface responsive to determining the particular target is a false target.

A method of operating a multi-mode radar system during multiple phases of autonomous aircraft operation may include, at an aircraft configured for autonomous operations and including a multi-mode radar system, the multi-mode radar system including a two-dimensional array of antenna elements: during an autonomous taxiing phase, operating the multi-mode radar system in a first radar mode to detect ground-based objects, and in response to a prediction of a collision between a ground-based object and the aircraft, executing a ground maneuver to change a direction of travel of the aircraft over ground. The method may further include, during an autonomous flight phase, operating the multi-mode radar system in a second radar mode to detect airborne objects, and in response to a prediction of a collision between an airborne object and the aircraft, executing a flight maneuver to change a direction of flight of the aircraft.

The system for assisting the avoidance of an excursion by an aircraft from a runway or taxiway of an aerodrome includes a unit for monitoring the aerodrome so as to allow the detection, by optical detection, of a characteristic element of a pathway, for determining a current relative position of a landing gear of the aircraft (AC) with respect to the detected characteristic element, and for detecting a future excursion from the pathway of the aerodrome by the aircraft (AC) on the basis of at least this current relative position, and a unit for assisting the implementation of an action for assisting the avoidance of said future excursion. The system is configured for providing assistance to the pilot of the aircraft by improving his awareness of a potential excursion, by warning and/or ground navigation aid messages, and by providing protection of last resort via automatic braking.
