    摘要: A system and methods for generating alerts in a terrain awareness and warning system (“TAWS”) in an aircraft, using data acquired from a forward-looking radar The system comprises a forward-looking imaging device, an airport database, a navigation system, a forward-looking terrain alert (“FLTA”) processor, and a crew alerting system. The FLTA processor determines a measured clearance altitude of a highest cell within an area and compares it with a required minimum clearance altitude; if the measured altitude is equal or less than the required altitude, the crew is alerted. Alternatively, a terrain database may be used. with the FLTA processor for determining if the aircraft descends below the minimum operating altitude or is predicted to do so and then generating an alert. A method is disclosed for generating TAWS alerts using elevation angle measured by the forward-looking radar and terrain data retrieved from a terrain database.

    摘要: An aircraft weather radar system can be used with a terrain avoidance system. The aircraft weather radar system is coupled to an antenna. A processor receives radar returns received by the antenna. The processor determines terrain elevation estimates for use with the terrain avoidance system from the radar returns. The terrain elevation estimates are compared to stored terrain elevation data used with the terrain avoidance system to verify position or to check the integrity of the stored elevation data. The processor can be part of a terrain avoidance system, a weather radar system, a navigation system, or can be a standalone system.

    摘要: Methods and systems of determining the altitude of an aircraft are provided. The method includes receiving data associated with aircraft position, a position of a first point and a second point on the runway, and an altitude of the first point and the second point, radar returns from the runway. The method includes determining a first range and second range between the aircraft, and the first point and the second point. The method includes determining a first angle and a second angle between the first point and second point, and the aircraft. The method includes determining a corrected angle. The method includes determining the altitude of the aircraft based on the corrected angle, the runway altitude of at least one of the first point and the second point, and at least one of the first range and the second range.
