    摘要: A system for enhancing the performance of a wireless communication device (WCD) while executing a direction of arrival (DoA) estimation. The performance may be improved through device management, and may include the collection of information from one or more sensors installed within the WCD. The sensor information may initially be used to determine an appropriate configuration for the device. Further, the sensor information may also be used to affect the behavior of the device while performing the DoA estimation.

    摘要: The invention relates to a method for verifying plotting results in case several signals (Sig1, Sig2) that have the same frequency are detected from different directions. According to said method, the signal characteristics of the signals (Sig1, Sig2) that are detected from different directions are compared such that a decision can be made based on said comparison of signals whether a reflection of the same transmitter (1, 2) occurs or if there are different transmitters (1, 2).

    摘要: Das erfindungsgemäße Verfahren zum Bestimmen eines Winkels (α1) der relativen Ausrichtung (AA1) eines Antennenfeldes (A1) einer ersten Funkstation (BS1), das wenigstens zwei Antennen aufweist, bezüglich einer Referenzrichtung (N), sieht vor, dass ein Winkel (γ) zwischen der ersten Funkstation (BS1) und einer zweiten Funkstation (BS2), bezogen auf die Referenzrichtung (N), ermittelt wird. Von der zweiten Funkstation (BS2) werden Signale (S1) zur ersten Funkstation (BS1) übertragen. Die Signale (S1) werden vom Antennenfeld (A1) der ersten Funkstation (BS1) empfangen und ein Empfangswinkel (β) wird zwischen den empfangenen Signalen (S1) und der Ausrichtung (AA1) des Antennenfelds (A1) bestimmt. Der Winkel (α1) wird als Differenz zwischen dem Winkel (γ ) des Richtungsvektors (V) und dem Empfangswinkel (β) bestimmt.

    摘要: A system for determining a bearing to a radio signal source includes four antennas and a computer. The computer accepts signals from the antennas as inputs and identifies which antenna is providing the largest amplitude signal and which antenna is providing the next-largest amplitude signal. These amplitudes are subtracted to determine an amplitude difference. The bearing is then determined in accordance with a linear function of the amplitude difference. The linear function is a model of the piece-wise linear approximation of antenna signal amplitudes accepted by the computer. The slope used in the linear function depends on the identity of the antenna that provides the largest amplitude signal. When the antenna that provides the largest amplitude signal is mounted on a fuselage oriented toward a curvature of the fuselage, as when facing port or starboard, then a different slope is used than when the antenna that provides the largest amplitude signal is mounted on the fuselage and oriented toward for or aft. More accurate bearing calculations result from use of different slopes accounting for fuselage shape and elevation angle resulting from a difference between the altitude of the system and the altitude of the radio signal source. Bearing may be used for aircraft traffic alert and collision avoidance systems.
