Chapter 1 / Introduction
_ _
• Create a missile simulator structure supporting separate missile models one
of which is a point mass missile for this research. These should access
alternative PN, CLOS and trajectory optimised guidance laws and autopilot
constraints found in Bank-to-Turn (BTT) and Skid-to-Turn (SST) missiles.
• Create a simulation infrastructure to support any simulator with dynamics
states, and in particular the aforementioned simulators. The infrastructure
should promote rapid development and use by the provision of interactive
controls, on-line data visualisation, self-contained utility software
interaction, and communication with external applications (MATLAB).
1.3 Document Structure
The scene is set by considering the political, military and economic factors
driving weapon system development; factors that underpin the objectives of
this research and the structure of the document. §2 to §7 follow the natural
design process shown in
Figure 1-2. At each stage
Targets
Sensors
Performance

alternative algorithms are
reviewed, down-selected and
implemented in simulators
embedded in the simulation
infrastructure described in §8,
a simulation used to explore
performance in §9.
Conclusions, future work,
references and bibliography
form §10 to §13. Basic
mathematics and simulation
functionality supporting the
main text appears in Appendix
A to Appendix I (§14 to §22).
There follows an overview of each chapter introducing some philosophical
discussion and placing the work in the overall context of missile system
design. This is then re-enforced by an in-situ precise to each chapter
expanding on the aims of the work and content. The main chapters
conclude by assessing the status of the work therein, conclusions drawn,
exploring closely related extensions and noting deficiencies.

Figure 1-2 : Document Structure
Missile design starts with the intended target; the critical element being the
ability to accurately predict its position from noisy measurements. The
system must be capable of detecting targets at ranges beyond that of the
defending missile, and react rapidly to the onset of target manoeuvres.
Nowadays targets are less co-operative than they once were being capable
of high acceleration avoidance manoeuvres, and radiating jamming signals
whilst ejecting all manner of decoys. The primary requirement imposed on
