摘要:
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 predicting and displaying targets based on height in relation to the wing, wingtip or other elements of the aircraft, such as engine nacelles. The location of ground obstacles is based on radar returns (from sensors deployed on the ownship), aircraft surveillance data, and/or an airport moving map database.
摘要:
The disclosed embodiments relate to methods and systems for avoiding a collision between an obstacle and a vehicle, such as an aircraft, on a ground surface. A processor receives a detection signal from one of a plurality of proximity sensors. The detection signal indicates that the obstacle has been detected. In response to receiving the detection signal, a video image signal is transmitted from the processor to a display in the cockpit of the aircraft. The video image signal corresponds to a particular video imager that is associated with the particular proximity sensor that detected the obstacle. A video image, of a particular region around the aircraft that includes the obstacle is displayed on a display. In response to receiving the detection signal, the processor can also transmit an alert signal, and a brake activation signal to activate a braking system to prevent the aircraft from colliding with the obstacle.

Systems and methods for aiding in pilot awareness of obstacles relative to aircraft features. An exemplary processor 36, 50 receives sensor information from one or more sensors 26 mounted in an aircraft feature (e.g. light modules 30), 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 54 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.

Radar return processing systems and methods are operable to process radar information when an installation vehicle (122) is operating in proximity to a surface area of interest. An exemplary embodiment reduces energy of an output pulse emitted from a radar system (410); receives a plurality of radar returns from a plurality of objects that reflect the reduced energy output pulses emitted from the radar system (410); determines a surface area of interest based upon at least a current location of the installation vehicle (122); and filters the radar returns generated by objects that are located outside of the surface area of interest. Optionally, some systems and methods may reduce a sweep range of an antenna from which the reduced energy output pulses are emitted.

The invention refers to a device and a method for monitoring a delimited area in order to detect if an undesired object is present within the area. The invention also refers to a use of the device. A first laser (10) is adapted to emit a laser pulse (B) of a determined wavelength over the area. A first photo sensor (11) is arranged to receive a reflected part of the laser pulse (B). An evaluation unit (20) is connected to the laser (10) and the photo sensor (11). The evaluation unit is arranged to measure the reflected part of the laser pulse (B) during a predetermined time period after the laser pulse has been emitted from the laser (10), to generate a signal depending on the measured reflected part and to process the generated signal in order to determine if an undesired object is present within the area.

In accordance with the principles of the invention, a surveillance radar is provided with a rotating, frequency squinting, end-fed slotted array antenna, which is caused to transmit a plurality of different carrier frequency pulses for successively illuminating specific antenna beam positions during rotation of the antenna. Upon reception of each radar signal return, a signal processor responsive to the frequency of each transmitted pulse and the mechanical pointing angle of the antenna at the time of transmission of each pulse, will determine the frequency dependent squint angle for the transmitted pulse and combine that angle with the instantaneous mechanical pointing angle of the antenna at the time of the pulse transmission, to determine the actual beam pointing angle for each pulse at the time of its transmission. A video signal processor groups together the pulse signal returns from physically adjacent ones of the actual beam pointing angles for common processing, i.e, integration, for improving the target detection performance of the radar system.
