Glossary _ _ The time taken to travel between points (a) and (b) is ( b t a ). When the time b difference is small it is permissible to use the delta notation ( ∆ ta ) to emphasis this fact. All variables are treated as “current”, for example, A(k) represents the current value of (A). When the same variable is required one or more algorithmic cycles ago separate variables are used in the simulation to represent A(k-1), A(k-2) etc. The following nomenclature associated with time is reserved for: • tS The time at which the missile is committed to launch and its sensors are activated. • tL The launch time when the firing chain is complete and first motion in the launcher is allowed. When dealing with time stamped asynchronous sensor measurements from different sources their source is identified, for example, (GRt) represents data from the ground radar. The measurement sources that may be referenced in this way are: • GR : Ground Radar • GS : Missile Gyroscope triad • AC : Missile Accelerometer triad • BA : Barometric altimeter • RA : Radar altimeter • SK : Seeker • FN : Control surface actuators • GP : NAVSTAR GPS • HM : Helmet mounted sight • AD : Air data system xlvi
1 Chapter 1 / Introduction _ _ Chapter 1 INTRODUCTION 1.1 Politics and Markets The Persian Gulf and Bosnia crises highlighted the importance of high precision stand-off weapon systems for “surgical” strikes against heavily defended, high value targets where collateral damage was politically unacceptable. The result has been mounting pressure from military leaders on research establishments for highly accurate munitions and standoff delivery systems. Stealthy delivery and high kill probabilities, without endangering the launch platform, will be key factors in future strategic planning. The demand for a single-shot capability has also promoted the importance of high reliability, and the emergence of reversionary mode capabilities. These pressures are influencing research into new missile systems with more emphasis on reliable designs and minimising collateral damage in limited military engagements. Weapon procurement agencies are now placing contracts that demand unprecedented levels of performance: • Expansion of operating envelopes with higher kill probability • All weather capability • Increased stealth • Resistance to sophisticated and multiple countermeasures • Ability to cope with highly manoeuvrable targets in a cluttered, multiple target environment These requirements are being met by new and emerging technologies combined with an unprecedented increase in computing power leading to the production of the most expensive and sophisticated weapon systems ever built. These are the so called “smart” weapons, integrated onto equally expensive launchers such as the EF2000 and Type 45 destroyer, in some cases at a cost beyond the capacity of any one country to produce. The proportion of the missile market by theatre of application is reproduced in Table 1-1 [P.1] . Over the last decade aerospace companies have merged, 1-1
