Abstract
A method of integrating ground-based radar information into an existing on-board aircraft radar system, where a radar indicator displays on-board radar images as a function of data words received from a receiver/transmitter of the on-board aircraft radar system, includes receiving ground-based radar data indicative of a ground-based radar image. A data word from an output stream of the receiver/transmitter of the on-board aircraft radar system is captured, with the captured data word being encoded in a first data word format. A position and heading of the aircraft is determined, and the ground-based radar data is sampled to obtain sampled ground-based radar data corresponding to the position and heading of the aircraft and to a radial scan angle for the captured data word. The sampled ground-based radar data and the captured data word are combined into a composite data word, with the composite data word being encoded in the first data word format. The composite data word is provided to the radar indicator for use in displaying a composite weather radar image having both on-board weather radar imagery and ground-based weather radar imagery.
