Abstract
This paper provides a comprehensive analysis of the performance of variable speed pureproportional navigation (PPN) guidance law. Although captur ability analysis of constant speed proportional navigation guidance law has been addressed by researchers, the engagement equations involved are highly nonlinear and solving them is a complex procedure, often resulting in complex functions. In the literature, a qualitative analysis technique is commonly employed to determine the capture conditions for the constant speed PPN guidance law without actually solving the equations of motion. However, in the case of varying interceptor velocity, which this paper addresses, has remained an open problem. In this paper a qualitative approach is used to determine the capture conditions of a variable speed interceptor which uses PPN to generate lateral acceleration commands to achieve interception. The paper utilizes a velocity variation method that encompasses switching between different velocity values, allowing for the identification of capture conditions that account for both abrupt and gradual velocity changes. © 2024 by Nobin Paul, Debasish Ghose.
