Proper design of receiver flight paths allows three-dimensional information to be encoded in sensed bistatic SAR phase history data. The authors show how the flight path taken by the receiving platform determines the resolution of nonparametric scene reconstructions and determines the variance of three-dimensional scattering centre location parameter estimates. Based on these relationships, a b...

Flight delays are not only a single point effect, but also affect related flights and airports through the air transportation network, causing large-scale flight delays. This article is aimed at Advance control of delays, that is, spread delay plan, prediction flight, provide advance reference for subsequent plan optimization, on basis prediction, adjust optimize use The aircraft path optimizat...

The problem of coverage of known space arises in a multitude of domains, including search and rescue, mapping, and surveillance. In many of these applications, it is desirable or even necessary for the solution to guarantee both the complete coverage of the free space, as well as the efficiency of the generated trajectory in terms of distance traveled. A novel algorithm is introduced, based on ...

The linear quadratic Gaussian-loop transfer recovery procedure is a classical method to desensibilise a system in closed loop with respect to disturbances and system uncertainty. Here an extension is discussed, which avoids the usual loss of performance in LTR, and which is also applicable for non-minimum phase systems. It is also shown how the idea can be extended to other control structures. ...

By using four independent rotors to provide lift and control moments, the quadrotor helicopter provides researchers with a small, mechanically simple and e↵ective vertical-flight platform. Typically, the lift and resultant torque due to each rotor can be approximated with simple aerodynamic models. Although these models have proven to be adequate in low advance-ratio flight conditions [1], they...

The present paper discusses simulation of Lévy semistationary (LSS) processes in the context of power markets. A disadvantage of applying numerical integration to obtain trajectories of LSS processes is that such a scheme is not iterative. We address this problem by introducing and analyzing a Fourier simulation scheme for obtaining trajectories of these processes in an iterative manner. Furthe...

a r t i c l e i n f o a b s t r a c t The closer proximity between airports and residential areas has created a growing attention regarding noise pollution. The noise abatement procedures established by the aeronautical authorities and the models for computing noise contours around airports are proof of that. There are also models for identifying aircraft taking off which have focused on the co...

This paper considers synthetic aperture radar (SAR) and other synthetic aperture imaging systems in which a backscattered wave is measured from positions along an arbitrary (known) flight path. The received backscattered signals are used to produce an image of the terrain. We assume a single-scattering model for the radar data, and we assume that the ground topography is known but not necessari...

This paper describes an integrated path planning and tracking control framework for autonomous verticaltake-off-and-landing (VTOL) vehicles, specially a quadrotor. The path planning adopts a receding horizon strategy to repeatedly plan a local trajectory that satisfies the vehicle dynamics and obstacle avoidance requirement. A tracking controller is then designed to track the optimised path. Th...

This paper proposes a method to reduce the error on the position given by the global position system (GPS), using a back-propagation artificial neural network (ANN) focused on a known linear path employed as target, which is used on the creation of path planning for an Unmanded Aereal Vehicle (UAV) tested on real time. This document shows the step by step development of the equations used and t...
