摘要:
A system and method for adjusting a target value for generating a vertical profile view in an aircraft weather radar system is provided. Processing electronics are configured to receive a target value for generating a vertical profile view of weather detected by the radar system. The processing electronics are also configured to adjust the target value to account for the motion of the aircraft and/or the motion of the detected weather.

A method of identifying a runway is disclosed. A first scan of an area of ground known to include a runway is performed. The first scan is accomplished using a weather radar system at a predetermined position. A first image is obtained from the first scan. The first image is stored in a memory. A second scan of an area of ground proposed to include the runway is performed. The second scan is accomplished using a weather radar system at what is believed to be the predetermined position. A second image is obtained from the second scan. The first image is retrieved from the memory. It is determined whether features in the first image correlate to features in the second image. A runway confirmation signal is sent to a pilot of the aircraft when there is a substantial certainty of correlation between the first and second images.

A aircraft hazard warning system or method can be utilized to determine a location of turbulence, hail or other hazard for an aircraft. A processor can process weather radar data representative of weather conditions. An avionic display can display graphical elements representing the weather conditions in response to the processor. The display can provide at least one first graphical element representing a size and a location of the turbulence at a first level. The display can provide at least one second graphical element representing a size and a location of the turbulence at a second level. The size of the second graphical element can have a minimal displayable size or can be determined using an inflation factor.

An aircraft hazard warning system configured to provide an indication of a hazard level to an electronic display includes an input configured to receive first input data and second input data. The first input data includes at least one of lightning detection data, radar reflectivity data, turbulence data, geographic location data, vertical structure analysis data, and temperature data. The second input data includes at least one of aircraft speed data and wing loading data. The system further includes processing electronics configured to determine a hazard level of the aircraft based on the first input data. The processing electronics updates at least one characteristic of the hazard level based on the second input data. The processing electronics provides an indication of the hazard level and updated characteristic to the electronic display. For example, the characteristic can be a color of indicators representing the first input data and can be modified based on the second input data.

The hazard warning system includes processing system for detecting an HVB condition. The aircraft warning system can use at least two types of radar returns and can measure decorrelation time to detect the HVB condition. Warnings of HVB conditions can allow an aircraft to avoid threats posed by such conditions including damage to aircraft equipment and engines.
摘要:
Systems and methods for displaying weather data relating to weather near an aircraft are provided. A method includes generating a three-dimensional weather profile of the weather near the aircraft based on reflectivity data from radar returns of a weather radar system of the aircraft. Generating the three-dimensional weather profile includes estimating weather data above a freezing layer height using a function that is based on a rate of reduction in reflectivity above the freezing layer. The method further includes transmitting weather display data to a display device, the weather display data being configured to cause the display device to display a visual representation of the three-dimensional weather profile.

A system for displaying vertical weather information on an aviation display aboard an aircraft, the aircraft including an aircraft radar system for scanning a target, is provided. The system includes processing electronics configured to receive a target selection from a user input device, to receive an altitude value of an echo top of the target based on radar return data, and to cause the altitude value to be displayed on plan view of weather images on an aviation display in response to the received target selection.
摘要:
A hazard detection system is for use on board an aircraft or other vehicle. The aircraft or other vehicle is disposed in an environment. The hazard detection system includes a circuit for receiving a charge accumulation signal indicative of the electric field associated with the environment. The circuit provides a warning in response to the charge accumulation signal. The warning is indicative of a hazard or potential hazard.

A vehicle system for determining an object threat level, includes a display and electronics configured to receive mission context data indicating an operational state of the vehicle. The electronics determines a threat level of the object in response to the mission context data. The electronics determines at least one recommended action in response to the threat level. The electronics provides an indication of the threat level and at least one recommended action to the display.
摘要:
A radar system includes an antenna. The radar system comprises a processor for providing an error in ground speed estimate based upon Doppler velocity data, and a transmitter. The frequency of radar signals from the transmitter is adjusted according to a velocity of the aircraft calculated using the error in ground speed estimate or using the error in ground speed estimate. The adjusted frequency can allow ground clutter to be removed by high pass filtering in one embodiment.
