Inflight aircraft vibration modes and their effect on aircraft radar cross section

Assessment of Aircraft Radar Cross-Section for Detection Analysis

Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. During World War II this struggle led to the development of a new tec...

Parameter Identification for Inflight Detection and Characterization of Aircraft Icing

Real Time Aircraft Radar Simulation

In this paper a real time aircraft radar simulation is presented. The implemented algorithms in a 3D synthesized environment used to recreate the visualization of radar console are shown. Objects in a typical scene are represented with polygons. The lobe is discretized with rays and the radar display is recreated solving ray-polygon intersections (Ray Shooting) and mapping them on the screen. F...

Vibration Data Analysis for a Commercial Aircraft

Using data from extensive vibrational tests of the new aircraft Saab 2000 a combined method for vibration analysis is studied. The method is based on a realization algorithm followed by standard prediction error methods (PEM). We nd that the realization algorithm gives good initial model parameter estimates that can be further improved by the use of PEM. We use the method to get insights into t...

Volumetric Radar Visualization System for Aircraft Landing

This article describes a novel approach to the real-time visualization of 3D imagery obtained from a 3D millimeter wave scanning radar. The MMW radar system employs a spinning antenna to generate a fan-shaped scanning pattern of the entire scene. The beams formed this way provide all weather 3D distance measurements (range/azimuth display) of objects as they appear on the ground. Using these im...
