This work obtains the capture region for a realistic true proportional navigation (RTPN) guidance law against a nonmaneuvering target where the assumption of constant closing velocity used in the guidance law is relaxed. This is a realistic departure from earlier treatments of true proportional navigation (TPN). A capture equation is obtained and a qualitative study carried out for both zero and non-zero miss-distances. The results obtained are shown to be significantly different from earlier studies, showing a degradation in the performance of the guidance law in the form of a reduced capture region. An example problem is computationally solved to obtain the exact capture region for various values of miss-distances.
