As new missile shield programs are put into place, the need increases for information on the latest systems design techniques and component technologies. This book explains how to properly assess war-fighting capability by examining detect, control, and engage processes in the context of the combat system. The authors present a systems engineering approach that can be applied to new systems under consideration and to existing operational system designs. Using this approach, performance tradeoffs can be made between the sensor (radar) and weapon (missile) that support the development, testing, and fielding of a balanced system. The text also addresses battlespace performance assessment.
