Closed-Form Solution to Guidance Problems

摘要

The effect of inertia of the guidance systems on the closed-form solution toguidance problems is investigated and an analytical solution is obtained. It indicates that the solution without considering the inertia is only a special form for long Line-of-Sight, However, this solution is also available to short Line-of-Sight. The unstability of angular rate of the Line-of-Sight and the reason for miss-distances are also expressed by this solution. The results can be used to analyse the effect of the proportional-navigation coefficient and the inertia of guidance system on miss-distances.
