## Summary:

This two-day course will help you understand and appreciate the unique challenges of both tactical and strategic missile guidance. So everyone can clearly understand the principles of missile guidance, concepts are derived mathematically, explained from a heuristic perspective, and illustrated with numerical examples and computer animations. Course mathematics and examples are non-intimidating. Computer source code is included so interested participants and duplicate the examples presented and explore issues beyond the scope of the course. The instructor’s textbook, Tactical and Strategic Missile Guidance, Fifth Edition, is included as well as a comprehensive set of course notes.

## What you will learn:

• Interceptor guidance system technology.
• How subsystems influence total system performance.
• Useful design relationships for rapid guidance system sizing.
• Using adjoints to analyze missile guidance systems.

## Who should attend:

This course will benefit managers, engineers, and programmers at all levels who work with or need to learn about interceptor guidance system technology. The heuristic arguments and numerous examples will give managers an appreciation for guidance so that they can interact effectively with specialists. Engineers and programmers will find the detailed course material and many source code listings (in FORTRAN, MATLAB, TrueBASIC and C) invaluable for both learning and reference. Attendees will receive a complete set of course notes as well as the textbook, Tactical and Strategic Missile Guidance, Fifth Edition.

## Course Outline:

1. Numerical Techniques. Review of all numerical techniques used in the course so that all material will be easy to understand. Simulation examples, with source code.
2. Fundamentals of Tactical Missile Guidance. How proportional navigation works and why it is an effective guidance law. Illustration of important closed-form solutions and their utility. Development of simplified engagement simulation and computer animation illustrating effectiveness of proportional navigation.
3. Method of Adjoints and the Homing Loop. Show how to construct an adjoint and how method of adjoints are used to analyze missile guidance systems and develop system error budgets
4. Noise Analysis. Illustrating computerized numerical techniques for simulating noise. Using the Monte Carlo technique for getting statistical performance projections by making many computer runs. How to use stochastic adjoints to get statistical performance projections in one computer run
5. Proportional Navigation and Miss Distance. Developing useful design relationships for rapid guidance system sizing. Showing how system dynamics, acceleration saturation and radome effects limit system performance.
6. Digital Noise Filters in the Homing Loop. Properties of simple digital noise filters (i.e., alpha-beta and alpha-beta gamma filters) and how they can work in a missile guidance system. How target maneuver can be estimated with range and line-of-sight information.
7. Advanced Guidance Laws. Deriving optimal guidance laws without optimal control theory. How missile acceleration requirements can be relaxed with augmented proportional navigation. How to compensate for system dynamics with optimal guidance.
8. Kalman Filters and the Homing Loop. Introducing the Kalman filter and showing how it is related to alpha-beta and alpha-beta gamma filters. Combining Kalman filters with optimal guidance. Showing how radome effects and time to go errors limit system performance.
9. Endoatmospheric Ballistic Targets. The importance of speed, re-entry angle, and ballistic coefficient in determining the deceleration of a ballistic target. Why decelerating targets are difficult to hit and guidance laws for dealing with them.
10. Extended Kalman Filtering. Performance comparisons of linear, linearized, and extended Kalman filters for estimating the ballistic coefficient of a decelerating ballistic target.
11. Tactical Zones. Introduction to the rocket equation and how drag limits system performance.
12. Strategic Considerations. Why the flat earth, constant gravity approximation is not appropriate for long range missiles. How Newton’s law of universal gravitation can be used and it’s impact on performance. Useful closed-form solutions for the required velocity and time of flight for strategic missiles.
13. Boosters. Using the rocket equation for booster sizing and an introduction to gravity turn steering for boosters
14. Lambert Guidance. Why the solution to Lambert’s problem is fundamental to steering a booster so that it will arrive at a desired location at a certain time. How to guide liquid fueled boosters with Lambert guidance and solid fueled boosters with GEM guidance.
15. Theater Missile Defense. Why ballistic targets are challenging- even if they don’t maneuver. How guidance laws can be developed to shape the trajectory and influence the impact angle.
