Abstract: The invention relates to a method, a device and a system, as well as to the use for the determination of a propagation direction of signals from an emitter to a receiver, particularly of the orientation and/or location of the receiver and/or of the emitter. Known methods have in common that direction of incidence or positions of only a limited number of emitters can be determined in a given time interval. Therefore, it is an object of the invention to provide a method, system and a device as well as a use, by means of which an easy position determination of as many devices, as desired, particularly of pure receivers is possible within a short time interval. This object is achieved by a method for the analysis of a wave field, wherein from at least one emission-device arrangement of an emitter, m signal sequences which are de-correlated against each other with A signals respectively, with a known phase relation to each other, are emitted via s different emission devices and/or from different places and/or orientations through an emission device of the emission-device arrangement, wherein s is greater than or equal to two, wherein A is greater than or equal to two and wherein particularly m is greater than or equal to two, and wherein at at least one, particularly mobile, receiver, particularly with only one reception device, reception is made, wherein an emission characteristic of the emission-device arrangement is being used, particularly in the form of at least one matrix, in order to determine the propagation direction of the signals to the receiver, particularly location and/or orientation of the receiver and/or of the sender, as seen relatively from the emitter.

Abstract: A method and a system are disclosed which utilize the polarization properties of electromagnetic fields for a determination of the direction to the source of the electromagnetic radiation. The method and system primarily use a particular antenna device with is associated receiver means for obtaining a wave field measurement. Assuming separate frequencies, the present method and system also make it possible to distinguish between several sources and register their separate polarizations simultaneously. At least three electric antennas, or three magnetic antennas, are used to measure the wave field. The registered field components need not be orthogonal to each other. The measured wave field is processed in accordance to predetermined formulae so that the propagation direction and other polarization characteristics, such as the spectral intensity I and the spectral degree of circular polarization rc, are derived. Furthermore the measurements need not be from more than one point in space. In this respect a one-point measurement is considered to be such that all antennas are well within a sphere of a wavelength scale.

Abstract: The invention relates to a method, device and system for the determination of a distance between two objects. It is known to repeatedly perform phase measurements, on the basis of a basis frequency, and, in the process, to increase the frequency in discrete steps and to thus exclude ambiguities, and to eventually obtain a distance-measurement value. The object of the present invention is to provide a corresponding method which makes a relatively accurate measurement possible, even with short measuring times, and even with objects which are moving with respect to one another, as occurs in practical applications. This is achieved by a method for distance measurement wherein from each of said at least two objects several signals are being emitted and analyzed with reference to their phase angel, said signals being at least partially emitted at different frequencies,said method being performed in at least two stages,wherein in a first stage at least one measurement with a frequency difference between frequencies is performed,said frequency differences being selected from a start-measurement frequency difference range and selection of a measurement-frequency difference range on the basis of such at least one measurement in said first stage, wherein in a second stage at least one measurement with a frequency difference between frequencies is performed,wherein said frequency differences are selected from the selected measurement-frequency difference range.
