TRUE proportional navigation (TPN) is a version of pro- portional navigation (PN) guidance law in which the missile lateral acceleration is applied perpendicular (normal) to the line of sight $(LOS)^1$ rather than to the missile velocity, as in the case of pure proportional navigation $(PPN).^2$ The TPN guidance law has been found to be analytically more tractable than the PPN guidance law. Guelman' obtained the capture region of TPN, for a nonmaneuvering target, defining capture in terms of zero miss-distance. However, guided missiles carry warheads that have a nonzero lethal radius and thus, in practical situations, it is possible to define capture in terms of an acceptable nonzero miss-distance. It is obvious that the capture region, as obtained by $Guelman,^1$ for zero miss-distance will expand further under this assumption. In a previous $paper,^3$ the capture region for TPN with nonzero miss-distance was obtained through extensive computations. In this Note we present a complete analytical solution to the problem.
