摘要： A system used for calibrating a direction-finding system. A device may include a signal receiver array. The signal receiver array may be utilized to determine the direction of arrival for signals emitted by other devices, and therefore, may be used to resolve the direction towards another device using the received signal. For example, an external tag may be utilized to emit a wireless signal usable inducing a response in each signal receiver of the signal receiver array. The device may also include one or more sensors usable in determining device orientation and/or a change in device orientation. The combined signal receiver response information and orientation information may be recorded at various instants as the device is moved for use in calibrating the antenna array.

摘要： Methods and systems for carrying different signals required for MIMO communication using a single coaxial cable between two endpoints of a distributed antenna system (DAS) network. Original MIMO signals having the same frequency are frequency-separated at a first endpoint of the network. The frequency-separated signals are propagated together over the single coaxial cable and then reconstructed to their original frequency at a second endpoint of the network.

摘要： A method and system are provided for calibrating on-board aviation equipment. An actual bearing from an aircraft to an automatic direction finder (ADF) station is determined. The aircraft is moved to a plurality of headings. An ADF bearing is determined from the aircraft to the ADF station at each of the plurality of headings. An error between the actual bearing and the ADF bearing at each heading is calculated. Then, an error function as a function of the heading of the aircraft is generated based at least in part on the calculated error.

摘要： A system is provided for reducing the time that a ship must be maintained on station to collect calibration data by reducing the frequencies at which calibration data is to be collected. Since it is impractical to consider calibrating over elevation angle and polarization on the full-scale ship, an accurate scale model and test facility are utilized, with surface wave data being collected from the ship before model-based data can be utilized. In the subject system, the number of calibration frequencies used aboard ship is dramatically reduced by as much as 80%, thus reducing the time the ship must be on station when doing a calibration run. In one embodiment, the shipboard surface wave data for one elevation and one polarization is combined with surface wave and sky wave data from the scale model to generate an array manifold or database used in subsequent direction finding activities. In order to minimize the frequencies at which shipboard data is collected, the set of frequencies used for shipboard calibration is limited to a subset of all the original calibration frequencies. The number of frequencies used for shipboard calibration is reduced by selecting frequencies which generate adjustment, or weighting factors which are valid over a wide bandwidth.
摘要翻译：提供了一种系统，用于减少船舶在车站上维护的时间，以通过减少要收集校准数据的频率来收集校准数据。由于在全尺度船舶上考虑对仰角和极化进行校准是不切实际的，所以使用精确的比例模型和测试设施，在利用基于模型的数据之前，从船上收集表面波数据。在主题系统中，船上使用的校准频率数量大大减少了80％，从而减少了在进行校准运行时船舶必须驻车的时间。在一个实施例中，用于一个高程和一个极化的船上表面波数据与来自比例模型的表面波和天波数据组合以产生用于后续方向发现活动的阵列歧管或数据库。为了最小化收集船上数据的频率，用于船上校准的频率集被限制为所有原始校准频率的一个子集。通过选择产生调整的频率或在宽带宽上有效的加权因子，减少了用于船上校准的频率数。
