Chapter 8 / Simulation
_ _
Having philosophised over an integrated approach to weapon system
development, the remainder of §8 focuses on the simulation infrastructure
provided for this research from which the AMIS was developed.
8.4 The Research Simulation Infrastructure
The program is a single entity whose modular design supports a number of
simulators embedded in the infrastructure at the level of state derivative
provision:
• Target trajectory simulator with airframe visualisation
• Sensor simulator
• Target state observation
• Missile state observation
• Missile model with conventional guidance
• Missile model with trajectory optimisation
The hierarchical nature of these “simulators”, each incorporating the
functionality of those preceding it, and the program controls isolating them,
are shown in Figure 8-5.

The algorithms, isolating controls, pre-requisite and default data for each
simulator are dealt with in detail in §2 to §7.
