A method for augmenting a noise-adaptive predictive proportional navigation terminal guidance scheme. In a second order configuration with noise adaptive varying gain parameters calculated as a function of time-to-go, this system implements an optimal control law to augment proportional navigation with a missile acceleration feedback term and a navigation ratio to account for first order Cited by: Abstract: This paper analyses the spatial characteristics of trajectories generated using Proportional Navigation (PN) guidance.
Using the monotonic regions of line-of-sight (LOS) parameters, necessary conditions are derived for avoiding static obstacles. H.M. Prasanna, D. GhoseRetro-proportional-navigation: a new guidance law for interception of high-speed targets J Guid Control, Dyn, 35 (), pp.

Besides the familiar. Keywords: LOS; LOS rate; Spatial Alignment 1. Introduction Most modern homing missiles make use of PN (proportional navigation) guidance law based on LOS (line of sight) vector and its rate .
The hybrid seeker system utilizes passive radar sensor and infrared image sensor to get the information of LOS and LOS : Jin Tang, Rui Ding. The proposed guidance law can be classified as an augmented proportional navigation guidance (PNG) law with the actual target acceleration component being replaced by its accurate estimate.
The character of the trajectory is shown to depend on an ``effective navigation constant'' proportional to the missile navigation constant (or gain) and the ratio of missile speed to closing speed; a value of this parameter greater than two is found to be.
Proportional Navigation. Proportional navigation is a guidance law that relies on the fact that two objects are bound to collide if their direct line of sight does not change as the range closes. To understand this, consider the example of two cars approaching the.
Proportional navigation has proved to be a useful guidance technique in several surface-to-air and air-to-air missile systems for interception of airborne targets. In this article, which is tutorial in nature, the basic theory of proportional navigation is presented and clarified.
The continuing evolving capability of guided weapons demands ever more knowledge of their development. This modern and comprehensive book covers the control aspect of guidance of missiles, torpedoes, robots, and even animal predators, from the viewpoint of the pursuer.
The text studies trajectories, zones of interception, the required manoeuvre effort, time of flight, launch envelopes, and. Written by an expert with more than 30 years of experience, Modern Missile Guidance contains new analytical results, obtained by the author, that can be used for analysis and design of missile guidance and control systems.
This book covers not just new methods nor is it merely a compilation of older methods, although it includes both. The book discusses, in a logical progression. Proportional navigation (also known as PN or Pro-Nav) is a guidance law (analogous to proportional control) used in some form or another by most homing air target missiles.
 It is based on the fact that two vehicles are on a collision course when their direct Line-of-Sight does not change direction as the range closes. PN dictates that the missile velocity vector should rotate at a rate. Abstract: Augmented proportional navigation requires the information of a target acceleration, which must be estimated by a filtering logic.
The process necessary accompanies a time lag, which degrades the guidance performance. A trade-off study between augmented and conventional proportional navigation is conducted with the time lag taken into consideration. Applied Min-Max Approach to Missile Guidance Topics covered include root clustering, disturbance rejection, guidance systems, and min-max control of uncertain and general parameters.

In addition, two variations on this guidance method are treated: one in which the commanded acceleration. v the Proportional Navigation Guidance law is also done. Afterwards, the roll, pitch and yaw autopilots are designed using the determined transfer functions.
Book Description. Design of Guidance and Control Systems for Tactical Missiles presents a modern, comprehensive study of the latest design methods for tactical missile guidance and control. It analyzes autopilot designs, seeker system designs, guidance laws and theories, and the internal and external disturbances affecting the performance factors of missile guidance control systems.
Proportional Navigation For short-to-medium range homing missiles the most widely used law in practice is proportional navigation (PN) guidance. The missile acceleration should nullify the line-of-sight (LOS) rate between the target and interceptor that is basic philosophy behind PN.
