THE main objective of guided missiles is to intercept targets with minimum miss distances
while optimizing the energy usage to increase their range. Current applications demand …

A capture region of the composite guidance law is analyzed for a missile equipped with a
strapdown seeker. The composite guidance law consists of a deviated pure pursuit …

Filtering of base motion disturbance from the sight line rate is necessary for homing
guidance of missiles. The present work proposes using a noninvasive seeker filter based on …

This paper examines the application of differential geometry to the engagement of both
nonmanoeuvring and manoeuvring targets. The kinematics of the engagement for both …

This brief presents the capturability analysis of a 3-D Retro-proportional navigation (Retro-
PN) guidance law, which uses a negative navigation constant (as against the usual positive …

The capturability of homing guidance schemes for missiles equipped with a strapdown
seeker is analyzed. For air-to-air engagement, the missiles should intercept a fast-moving …

It is a comparatively convenient technique to investigate the motion of a particle with the help
of the differential geometry theory, rather than directly decomposing the motion in the …

Pure proportional navigation (PPN) is suitable for endoatmospheric interceptions, for its
commanded acceleration is perpendicular to interceptor velocity. However, if the target is …

True proportional navigation (TPN) guidance law is widely used for exoatmospheric
interception, for its robustness and ease of implementation. The performance of TPN against …

This brief discusses the convergence analysis of proportional navigation (PN) guidance law
in the presence of delayed line-of-sight (LOS) rate information. The delay in the LOS rate is …
