This paper examines the advantages of adding On-Board Training functions to programmable Electronic Combat devices.

The flexibility now built into many EC devices makes it possible to modify and add to the basic functions of the devices and to communicate with other devices. On-Board Training functions can be added to such devices. For Electronic Combat equipment, On-Board Training (OBT) involves injecting simulated radar signals into EC devices to provide realistic threat displays and responses for training purposes. A hypothetical application is described. Alternative implementations on several levels of complexity are discussed. An OBT retrofit application is described, the On-Board Electronic Warfare Simulator (OBEWS), which is being designed for the U.S. Air Force. Aspects of OBT training effectiveness and system configuration are discussed. Problems with OBT systems are examined - task definition, capacity limitations in host equipment, interaction with basic operational functions, and long-term maintenance. Special aspects of land-based and sea-based OBT are presented.
