    摘要: A method of adjusting a position of an antenna to reduce a position error comprises receiving first data associated with first returns associated with a first portion of an antenna. The method further comprises receiving second data associated with second returns associated with a second portion of the antenna, wherein the first portion is different than, intersects with, or includes the second portion. The method further comprises determining the angle to the terrain using the first and second data, whereby the angle is used to adjust or compensate for the position error of the antenna.

    摘要: An aircraft weather radar system for displaying an indication of a threat level presented by an obstacle to the aircraft on an electronic display. The weather radar system includes a radar antenna configured to receive radar returns from a radar sweep. The weather radar system additionally includes processing electronics configured to determine a movement vector of the obstacle using the radar returns. The processing electronics are further configured to determine the threat level of the obstacle to the aircraft based on the determined movement vector, to generate parameters for an indication based on the determined threat level and to cause the indication to be displayed on an electronic display.

    摘要: A method of detecting weather on an aircraft uses a weather radar system. The method includes determining a location of a reflective radar target, accessing a database having stored information relating to ground clutter of a reflective radar target, retrieving weather radar information associated with the location, and automatically adjusting the weather radar return threshold in response to the information. The method can adjust a threshold for a weather radar display, adjust a weather radar signal gain, adjust a tilt angle of the weather radar, or adjust a ground clutter suppression threshold. The method can be implemented by hardware and/or software.

    摘要: A weather radar system is capable of mitigating the effects of spurious reflections caused by a reflection lobe. Processing electronics can be used to sense weather and to identify spurious reflections caused by the reflection lobe. The reflection lobe can be caused by antennae or radome characteristics. The weather radar system can include a display that provides visual indicia of the weather with mitigation of the spurious reflections.

    摘要: An airborne weather radar system that detects potentially hazardous weather conditions associated with storms and includes a radar display featuring visual indications of these conditions. The radar display includes a vertical situation display having iconal representations and symbolic icons indicative hazardous weather conditions and aviation hazards along the aircraft's flight path not otherwise immediately apparent or shown on standard weather radar displays. The system includes processes for detecting and predicting hazardous weather conditions such as overshooting thunderstorm tops and vaulted thunderstorm energy and serious hazards such as turbulence and hail.
