This paper introduces an adaptive guidance law for intercepting a maneuvering target using information from an imaging seeker. The relative missile-target kinematics is represented in the line-of-sight (LOS) frame and the image information instead of the relative range is introduced to formulate the interception problem as an adaptive control problem with an unknown control coefficient. Conside...

Maneuverability describes a vehicle’s ability to change course or turn. Maneuverability of conventional underwater vehicles, such as torpedoes, can be determined by altering the position and length of control fins. To perform large-area surveying tasks, autonomous underwater vehicles (AUVs) generally require different maneuverability characteristics in their vertical and horizontal planes of mo...

Support vector machines have been validated as an efficient artificial intelligent algorithm for solving classification and regression problems on account of their simple model structure, good generalization and global optimal solution. However, their on-line performances are not yet widely used. A simple on-line algorithm named incremental least square support vector machines is put forward by...

Abstract: In this report, we propose compressed sensing inverse synthetic aperture radar (ISAR) imaging in the presence of highly maneuvering motion using a modified orthogonal matching pursuit (OMP) reconstruction algorithm. Unlike existing methods where motion is limited to firstor second-order phase terms, we take into account realistic motion of a maneuvering target that can involve a third...

This paper presents a simple and efficient approach to the computation of avoidance maneuvers among moving obstacles. The method is discussed for the case of a single maneuvering object avoiding several obstacles moving on known linear trajectories. The original dynamic problem is transformed into several static problems using the relative velocity between the maneuvering object and each obstac...

This communication proposes a gain design method of an α-β filter with linear frequencymodulated (LFM) waveforms to achieve optimal range prediction (tracking) of maneuvering targets in steady-state. First, a steady-state root-mean-square (RMS) prediction error, called an RMS-index, is analytically derived for a constant-acceleration target. Next, a design method of the optimal gains that minim...

New helmet-mounted devices (such as night-vision goggles, laser eye protection, etc.) have created new safety hazards for pilots during ejection or high G maneuvering. In order to prevent the resulting head/neck injuries, this study extends the air-bag protection system developed for ground vehicles to a neck mounted system for aircrew personnel. Results, carried out by computer biodynamic simu...

In this paper, we propose a nonlinear guidance law for missiles against maneuvering targets. First, we derive the equations of motion described in the line-of-sight reference frame and then we define the equilibrium subspace of the nonlinear system to guarantee target interception within a finite time. Using Sontag’s formula, we derive a nonlinear guidance law that always delivers the state to ...

In this paper, a novel interactive multiple model particle filter (IMMPF) is developed after a Bayesian estimator for maneuvering target tracking in clutter is derived theoretically. In this new algorithm, base state estimation and modal state estimation are completely separated to control the number of particles in each maneuvering mode. Only continuous-valued particles are used to numerically...

Maneuver detection is a very important task for maintaining the catalog of the orbital objects and space situational awareness. This paper mainly focuses on the typical maneuver scenario, where space objects only perform tangential orbital maneuvers during a relative long gap. Particularly, only two classical and commonly applied orbital transition manners are considered, i.e. the twice tangent...
