Lyapunov-Based Pursuit Guidance Law with Impact Angle Constraint
This paper presents Lyapunov-based pursuit guidance law against stationary targets. To design a nonlinear guidance law, Lyapunov candidate function is introduced to reduce the angle between the velocity vector of a missile and the distance vector between the missile and the target. Therefore, the proposed guidance laws have the characteristic of pursuit guidance. To attack a target from a prede...
متن کاملMulti-Observations Initial Orbit Determination based on Angle-Only Measurements
A new approach with the ability to use the multiple observations based on the least square approach has been proposed for initial orbit determination. This approach considers the Earth’s Oblateness by using the developed Lagrange coefficients. The efficiency of the proposed method has been tested in two scenarios. The first scenario is to use the simulated and the second one is to utilize the r...
متن کاملSensor Networks for Optimal Target Localization with Bearings-Only Measurements in Constrained Three-Dimensional Scenarios
In this paper, we address the problem of determining the optimal geometric configuration of an acoustic sensor network that will maximize the angle-related information available for underwater target positioning. In the set-up adopted, a set of autonomous vehicles carries a network of acoustic units that measure the elevation and azimuth angles between a target and each of the receivers on boar...
متن کاملOptimal Sensor Trajectories in Bearings-Only Tracking
We consider the problem of determining sensor trajectories in the bearings-only tracking of an uncertain target. This work differs from previous research in that we allow the target dynamics to be both uncertain and random; and also consider multi-sensor scenarios. The basis of our technique is to control a measure of estimation error based on the Posterior Cramér-Rao lower bound (PCRLB), and w...
متن کامل3D Passive Bearings-Only Emitter Localization Using Crude Angle-of-Arrival Measurements
Abstract. This paper derives three-dimensional passive bearings-only localization algorithms and examines their performance in the presence of large measurement noise by way of simulations. Among the algorithms studied, an iterative Gauss-Newton (GN) implementation of the maximum likelihood (ML) estimator is shown to have the best localization performance. In order to reduce the computational c...
