optimisation that can be undertaken is introduced for assessing real-time<br />

system performance.<br />

1.3.6 Chapter 8 : Simulation<br />

The discussion on the role of simulation for developing and proving modern<br />

weapon systems is extended. To recap, the complexity of missile systems<br />

has raised the status of the validated simulations required to predict<br />

performance over an extended envelope without resort to expensive trials.<br />

This is discussed in the context of creating a simulation environment<br />

capable of supporting several systems with common launcher interfaces and<br />

a shared infrastructure cost. §8 describes such an infrastructure designed to<br />

support any dynamical model covering external<br />

and interactive control, on-line visualisation,<br />

internal data communication, I/O facilities,<br />

their interaction with external applications, post<br />

processing and Monte-Carlo ensemble analysis<br />

supported by:<br />

• Software configuration<br />

• Software utilities that are the basis for rapid<br />

model development (Appendix I).<br />

• External interface with MATLAB for graphics,<br />

time series and signal analysis.<br />

Within this infrastructure reside the “separate”<br />

simulators shown in Figure 1-3 forming a<br />

common thread through §2 to §7, each<br />

incorporating the functionality of those<br />

preceding it, and designed so that they can be<br />

executed in isolation:<br />

• Target trajectory generation.<br />

• Sensor modelling – generic error model<br />

characterisation.<br />

• Target state observation – multiple-model track<br />

formation.<br />

Embedded Simulators<br />

• Missile state observation – central fusion of up-linked and sensor data.<br />

• Missile simulator – flight dynamics, PN and CLOS guidance, and open loop<br />

trajectory optimisation.<br />

The interaction between modern air-launched missiles and their launchers is<br />

discussed in the context of a new breed of simulation. In the mid-90s<br />

MBDA agreed that this infrastructure and many of the utilities and generic<br />

sensor models created should form the basis for the Aircraft and Missile<br />
