23 Mar 2009TL;DR: The usefulness of an iterative back projection technique has been demonstrated for both theoretical and real measured test cases, and other applications for antenna diagnostic tools, such as phased array calibration and position error correction, are discussed.
Abstract: There are several methods to calculate the antenna aperture excitation from measured near- or far-field data. The usefulness of an iterative back projection technique has been demonstrated for both theoretical and real measured test cases. Other applications for antenna diagnostic tools, such as phased array calibration and position error correction, are also discussed.

15 Nov 2010TL;DR: In this paper, the authors address the modeling of radar absorbing composite layers with ferromagnetic inclusions and discuss the applicability of mixing formulas to determine the effective permeability of the composite material.
Abstract: This paper addresses the modelling of radar absorbing composite layers with ferromagnetic inclusions. The radar absorbing properties of these layers are strongly determined by the effective permeability of the composite material. The applicability of mixing formulas is discussed to determine the effective permeability. Furthermore, the RF-frequency behaviour of ferromagnetic inclusions is described. The mixing formulas and the RF-frequency behaviour of ferromagnetic inclusions are used in tools to support the EM design of radar absorbing composite layers.

16 Aug 2006TL;DR: In this paper, a method for the manufacture of composite articles comprising a composite plate and at least one fitting is described, where the composite material layer (9) forms the walls of a stiffener and encloses the fitting so as to support it.
Abstract: The present invention relates to a method for the manufacture of a composite article comprising a composite plate ( 1 ) and at least one fitting ( 4 ). The method is characterized by the steps of arranging at least one former on said composite plate ( 1 ), arranging at least one fitting ( 4 ) on said composite plate ( 1 ), producing a lay-up by applying a composite material layer ( 9 ) least partly covering an external surface of the former and of the fitting, and curing the layup in a curing process. After curing, said composite material layer ( 9 ) forms the walls of a stiffener and at least partly encloses the fitting so as to support it in a predetermined position.

20 Nov 2012TL;DR: In this paper, an airfoil article including a composite skin (5) forming a leading edge (4), the composite skin was during use subjected to an airflow meeting the leading edge at stagnation points (SP), where the airflow was divided into a first (a1) and second (a2) airflow, and at which stagnation points the airflow swirls.
Abstract: The invention regards an airfoil article including a composite skin (5) forming a leading edge (4), the composite skin (5) being during use subjected to an airflow (a) meeting the leading edge (4) at stagnation points (SP), where the airflow (a) being divided into a first (a1) and second (a2) airflow, and at which stagnation points (SP) the airflow swirls. The leading edge (4) comprises a flush elongated member (9, 9'…9''''', 30, 32, 36, 38, 39), the elongated member having an extension being parallel with an imaginary line (IL) intersecting with the stagnation points (SP). The elongated member is arranged primarily for erosion protection.

08 Sep 2009TL;DR: In this paper, a system and method for mapping a target scene by means of scanning radar utilizing the Doppler effect that arises in the event of movement between radar and target scene, where the movement of a platform upon which the radar's antenna is mounted is calculated utilizing navigation data obtained for the platform.
Abstract: A system and method for mapping a target scene by means of scanning radar utilizing the Doppler effect that arises in the event of movement between radar and target scene, where the movement of a platform upon which the radar's antenna is mounted is calculated utilizing navigation data obtained for the platform. The system and method can generate high-resolution radar images in an almost forward-looking application. This is achieved by introducing an approach compensation (7), in which the signal quantity received by the radar which is related to transmitted pulses is transformed pulse by pulse to a corresponding movement-corrected signal quantity by displacement in time and phase, dependent upon the platform's movement along an imaginary platform movement directed in such a way that the antenna's momentary direction is essentially 90° to the direction of the movement of the imaginary platform.
