 The RADAR Simulation Software!


PREP uses CBT to enable students and engineers to vary radar parameters, and to observe the effects on
active radar screens.  PREP uses standard displays and signal processing techniques, which help to familiarize
 the user with typical modern pulsed radar systems, and an introduction to Electronic Warfare (EW).

 PREP consists of several simulated Line Replaceable Units (LRUs), as follows:

A near real-time Simulator is included, with a user definable target environment, and an electronic Blake Chart,
