Framework for Low-Observable Trajectory Generation in Presence of Multiple Radars
TL;DR: The paper presents a formulation of the trajectory generation task as an optimal control problem, where temporal constraints allow periods of high observability interspersed with periods of low observability, and shows that the success of nonlinear trajectory generation on the proposed low-observable trajectory generation problem depends upon an accurate parameterization of the guidance data.

Nonlinear trajectory generation for unmanned air vehicles with multiple radars
TL;DR: The overall probability of detection function is used, both because it aids in the extension to multiple radar systems and because it is a more direct measure of the desirable optimization criteria.
Journal ArticleDOI
Compound helicopter multi-rotor dynamic radar cross section response analysis
TL;DR: The proposed MDS method is effective and efficient for the dynamic electromagnetic scattering of aircraft operating on individual rotor or multi-axis rotor-type targets, and the disc tilt or attitude angle affects this periodic and full-machine dynamic scattering.

On Modeling RCS of Aircraft for Flight Simulation
Björn Persson,Martin Norsell +1 more
TL;DR: High-resolution RCS matrices were used in an investigation of RCS matrix resolution, and an evaluation of different bilinear interpolation methods is presented, finding that the smallest RCS interpolation error was obtained using splines.
Journal ArticleDOI
Multistage Trajectory Optimization with Radar Range Constraints
TL;DR: In this article, the problem of finding an optimal aircraft trajectory for long-distance flights in three dimensions subject to radar detection constraints is considered and a general point-mass model is not suitable because the time discretization needs to be very fine to resolve the rigid-body dynamics resulting in very large optimization problems.

Overview of Low Observable Technology and Its Effects on Combat Aircraft Survivability
TL;DR: In this paper, the authors show how low observable (LO) dramatically improves combat aircraft survivability by reducing an air defense's ability to detect, track, intercept, and destroy an LO aircraft.

Flight testing an optimal trajectory for the Saab J35 Draken
TL;DR: A simple test was performed to demonstrate the culties involved in trying to follow a numerically computed trajectory in a real test, and the model and numerical implementation used to calculate optimal trajectories are described.
