Definitions

  • the invention relates to a high-frequency measuring hall for measuring large DUTs.
  • High-frequency measuring chambers or halls are required for the measurement of particularly large measuring objects, such as for example of operational aircraft, mobile radar systems and other large objects, which influence an electromagnetic field by reflection of high-frequency radiation.
  • the measurement inside halls instead of outdoors is necessary to increase the measuring accuracy due to the climate protection guaranteed thereby.
  • B. measuring equipment or parts of measuring equipment is suitable, which ensures the required climate protection and reduces the need for costly absorber materials.
  • a high-frequency measurement hall for measuring large DUTs wherein the high-frequency measurement hall consists of a TragluftgeInstituten membrane or textile construction with spherical or ellipsoidal contour, which is largely transparent to electromagnetic radiation.
  • An advantage of the invention is that remaining reflected portions of electromagnetic radiation are largely directed towards the ground by the spherical or elliptical dome construction.
  • Another advantage of the invention is the use of new textiles or membranes in a nearly radioelectrically transparent air-inflated hall, which can largely dispense with the use of costly absorber materials to suppress room reflections on the ceiling and walls.
  • a high-frequency measuring hall is disclosed, wherein furthermore the floor of the high-frequency measuring hall is at least partially designed with absorber material for absorbing the electromagnetic radiation still reflected from the inside of the surface.
  • Another advantage of the invention is that the bottom of the high-frequency measurement hall is at least partially, i. partially or completely covered with absorbent materials or designed to absorb the remaining reflected portions of the electromagnetic radiation, which are passed through the spherical or elliptical dome construction largely in the direction of the ground.
  • a high-frequency measuring hall is disclosed, wherein the high-frequency measuring hall further has at least one lock for the introduction of large measuring objects.
  • a high-frequency measuring hall wherein the high-frequency measuring hall further has at least one lock for the access of persons.
  • a high-frequency measuring hall is disclosed, wherein the high-frequency measuring hall is set up to accommodate at least parts of at least one high-frequency measuring system including at least one measuring object.
  • the high-frequency measuring system according to the invention may comprise whole or parts of a high-frequency measuring system including at least one measuring object. It may also be more than a high-frequency measuring system completely or partially housed in the high-frequency measuring hall.
  • a high-frequency measuring hall is disclosed, wherein the high-frequency measuring hall is set up to accommodate at least parts of at least one high-frequency measuring system without a measuring object.
  • a further advantage of the invention is that the disclosed high-frequency measuring hall allows a cost-effective climate protection, which is compatible with the high-frequency measuring technique and also allows the complete or partial housing of a measuring system.
  • FIG. 5 shows plan views of a spherical measuring hall, 6 outer views of a semicircular supporting air construction for accommodating a protective radio frequency measuring device,
  • One aspect of the invention is that, in contrast to conventional building structures, carrying air-supported textile structures are used as a measuring chamber, in which not only the measurement object but also the entire measuring section can be accommodated.
  • supporting air-supported textile constructions or membranes can be used up to a size of 600 m ⁇ 200 m base area and thus allow the accommodation of large measuring objects themselves, but also the corresponding ones large antenna measuring systems, such as complete far-field measuring lines or so-called compact ranges and near-field measuring systems.
  • the invention comprises the features that the spherical or elliptical contour of the spatial delimitation, the electromagnetic energy impinging there is either transmitted outwards through the textile or reflected to a sufficiently high proportion on the floor of the measuring hall and by the absorber materials lying there is absorbed.
  • FIG. 1 shows the reflection behavior of the airfoil hall according to the invention at higher frequencies.
  • the drawing illustrates the advantageous reflection effects of the spherical or ellipsoidal delimitation on the hall floor according to the invention high-frequency measuring hall. This reflection behavior was confirmed by simulation, for example. Even the construction itself yields further considerable cost savings of up to approx. 70% in the construction compared to a hangar-like building and a supporting air-supported hall.
  • Figure 2 shows a typical Tragluftge Optimize hall with locks for the introduction of large objects to be measured and locks for people access, designed for use as a high-frequency measuring chamber.
  • FIG. 3 shows an arrangement for accommodating a so-called compact-range measuring system in the air-inflated hall or high-frequency measuring hall according to the invention.
  • the bottom plate of the air-inflated hall is shown.
  • the climate cover is only hinted at to allow a view into the interior of the high-frequency measuring hall according to the invention.
  • Figure 3 shows a high frequency feed system for illuminating the reflector and a reflector. Furthermore, a measuring zone and a lock are shown.
  • FIG. 4 shows typical aspect ratios of a truss-supported high-frequency measuring hall according to the invention.
  • the exemplary size design of the climate envelope is rather conservative. The sizing could still be reduced.
  • FIG. 5 shows plan views of a spherical measuring hall, showing an arrangement with a half climate envelope and an arrangement without an air envelope.
  • a high frequency feed system for illuminating the reflector and a reflector; Furthermore, a measuring zone and a lock are shown.
  • FIG. 6 shows external views of a semicircular supporting air construction for accommodating a protective radio frequency measuring device.
  • a high-frequency transparent film or textile can be used.
  • FIG. 7 shows external views of a semicircular supporting air construction for accommodating a high-frequency measuring device requiring protection with high-frequency transparent foil (not shown).
  • FIG. 10 shows the arrangements of FIGS. 7 to 9 in a three-dimensional representation
  • FIG. 11 shows the arrangement of a radiation-technically optimized accommodation of protection-requiring measuring devices.
  • FIG. 11 shows a hemispherical supporting air construction.
  • Such a hemispherical carrying air construction can be designed according to the invention with a special textile for carrying out the high-frequency beam path of a measuring system.
  • FIG. 12 shows the arrangement of a radiation-optimized accommodation of sensitive measuring devices with typical size ratios and views.
  • the high-frequency measuring hall according to the invention has, inter alia, the advantage of increased accuracy due to reduced humidities and wind and direct sunlight, the higher availability of the measuring system, as weather independent, the use of less expensive indoor equipment, lower maintenance costs due to lower pollution, the longer life of the measuring equipment and the given visual protection.

Abstract

La présente invention concerne une salle de mesure haute fréquence pour effectuer des mesures sur des objets de grande taille. Selon l'invention, la salle consiste en une structure de type membrane ou textile gonflable ayant un contour sphérique ou ellipsoïde, et est dans une large mesure perméable au rayonnement électromagnétique, et le sol à l'intérieur de cette salle, est revêtu d'une matière absorbante destinée à absorber le rayonnement électromagnétique qui est encore réfléchi par le côté intérieur de la surface. On obtient une structure qui s'avère économique vis-à-vis de l'état de la technique, d'une part grâce à la structure elle-même, et d'autre part grâce à la matière utilisée, dans une large mesure perméable au rayonnement électromagnétique, ce qui permet de supprimer les frais élevés liés à la matière absorbante.
