This study presents a comprehensive analysis of biased proportional navigation guidance laws with variable gain in the bias command that achieve stationary target interception desired impact angle under restriction permissible look angle. More specifically, this investigates shaping approach, which takes function given by product factors range and The linear feedback fractional power impact-ang...

The paper proposes a two-dimensional impact time control cooperative guidance law under constant velocity and three-dimensional time-varying velocity, which can both improve the penetration ability combat effectiveness of multi-missile systems adapt to complex variable future warfare. First, more accurate time-to-go estimation method is proposed, based on modified proportional navigational (MPN...

A data-driven statistical analysis of the missile’s capture region is performed. The initial geometric configuration for pursuer missile against a target in which can intercept while satisfying specific constraints. verification approach has advantages over analytic that it deal with various guidance algorithms and maneuver utilizing numerical simulator. In this study, model constructed using G...

The aim of this paper is to present a new three-dimensional proportional-pursuit coupled (PP) guidance law to track highly maneuverable aircraft. Utilizing a 3-D polar coordinate frame, the PP guidance law is formed by collecting proportional navigation guidance in Z-R plane and pursuit guidance in X-Y plane. Feedback linearization control method to solve the guidance accelerations is used to i...

In their article, Gomez-Marin and Louis (2014) found that runs in Drosophila larval chemotaxis bend toward the direction of higher concentration. This steering process called weathervaning or klinotaxis was previously discovered in the worm C. elegans (Ward, 1973; Iino and Yoshida, 2009) and raises the question: how is it performed? Although Gomez-Marin and Louis (2014) found that run orientati...

Cognitive deficits in older adults attributable to Alzheimer's disease (AD) pathology are featured early on by hippocampal impairment. Among these individuals, deterioration in spatial navigation, manifested by poor hippocampus-dependent allocentric navigation, may occur well before the clinical onset of dementia. Our aim was to determine whether allocentric spatial navigation impairment would ...

This study presents the design of three-dimensional biased proportional navigation guidance laws for arrival at a stationary target along desired direction based on spatial rotation predicted final velocity vector. The focus is full constructive derivation using vector-form expressions without introducing local representation such as Euler angles or quaternions. proposed approach synthesises bi...
