The use of radar simulators in the royal navy

The paper describes a synthetic training system developed for the Royal Navy to provide a means of semi-realistic study of tactical problems involving ships and aircraft. The requirements of realism and accuracy necessary in such a trainer are considered and the paper goes on to describe the radar simulator on which the system is based, together with other circuits devised to satisfy these requirements. The particular system described has been developed to meet somewhat specialized requirements for the Royal Navy and details of the number of targets used, speed, height and radar range have been omitted for security reasons.
