System for and method of displaying an image derived from weather radar data

摘要

An apparatus is for use with an aircraft radar system having a radar antenna. The apparatus comprises processing electronics configured to provide image data associated with an image associated with radar return data from the radar system. The radar return data is updated at a first frequency. The processing electronics are configured to update the image data at a second frequency greater than the first frequency.

1. An apparatus for use with an aircraft radar system of an aircraft having a radar antenna, the apparatus comprising:
a display and processing electronics comprising an image merge module and a data interpolation module and configured to: (1) provide first image data associated with radar return data from the radar system, the first image data representing terrain, the radar return data being updated at a first frequency; (2) receive second image data representing the terrain and associated with a synthetic image system at a second frequency greater than the first frequency; (3) perform conformal interpolation of the first image data with respect to position of the aircraft at the second frequency to provide interpolated image data; (4) merge the second data and the interpolated image data at the second frequency to provide merged image data indicative of at least one image associated with the interpolated image data and at least one image associated with the second image data; and (5) provide the merged image data to cause the display to display a merged terrain image associated with the merged image data, the merged image data being provided at the second frequency.
