There has been a growing interest in the use of Airborne Weather Radar simulation from both military and commercial operators of transport aircraft. This interest, in part, stems from the need to train aircrews to fly through weather conditions, which at one time would have been given a "wide berth", without sacrificing safety margins. This change in requirement has arisen due to escalating fuel costs.

To date, the cost of full radar simulation has restricted its use to the more sophisticated aircraft simulators. The Link-Miles Division of Singer has developed a low cost or simple Weather Radar Simulator for use on transport aircraft simulators. This paper describes the simulation techniques adopted and shows how recent advances in semi-conductor technology have been incorporated to produce a system capable of being fully integrated into an aircraft simulator.
