Minimum Effort Pursuit/Evasion Guidance with Specified Miss Distance

What is it about?

Most optimal guidance laws are derived by optimizing performance, while penalizing or setting bounds on the guidance command. This paper derives guidance laws for both pursuit and evasion that minimize guidance effort while specifying a bound for the performance. In case of pursuit, the bound is a maximum for the miss distance. In case of evasion, the bound is a minimum for the miss distance.

Why is it important?

Not only is this a quite logical point of view, but it allows to treat pursuit and evasion completely symmetrical, which is not always the case in optimal guidance theory.
