摘要： The invention relates to a method and device for estimating angle information (50) of a received ultra-wideband wireless signal. Upon reception of a wireless signal emitted from a transmitting device (20) with known sounding sequence, the receiving device (10) estimates the channel impulse response (CIR), selects a portion of the channel impulse response (CIR), and estimates angle information (50) given the angle-dependent antenna transfer functions of either the transmitting device (20), the receiving device (10), or both. For this, the selected portion of the channel impulse response of the signal is fed into a neural network (73) which outputs an angle information probability distribution for the ultra-wideband wireless signal (50).

摘要： A satellite tracking system and method, a three-point peaking technique is used to determine the direction of a satellite 50 which includes a signal source. A Kalman filter is used to minimize the effects of noise in the received signal during the three-point peaking operation. This determination may be made at any time. Once the position of a satellite 50 has been determined twice over a time interval, its future position may be estimated by an adaptive continuous step track technique, using a Kalman filter, which assumes that the satellite moves uniformly with time as viewed from the antenna.

摘要： A system and a method are disclosed for estimating antenna misalignments in a line-of-sight wireless communication system and using the estimated antenna misalignments to form an optimal beam that may provide the best performance based on the channel conditions. A receiver determines a rotational estimate and a translational estimate of the receiver with respect to a transmitter, and sends feedback information to the transmitter that is used to determine an optimal beamforming matrix for LOS communications between the receiver and the transmitter. The feedback information includes estimated rotational angles and an estimated translational distance between the receiver and the transmitter, or includes an offset angle between a first plane of antennas of the receiver and a second plane of antennas of the transmitter, a normal vector of the first plane of antennas and the estimated translational distance. The antennas may be antenna arrays or single-element antennas.

摘要： The invention relates to a method for determining an angle of arrival of a received radioelectric signal implemented by a receiving antenna system including either one rotating antenna having at least two receiving channels, or two rotating antennas with a same speed each having a receiving channel, and having different antenna diagrams. The method includes, in the operational phase, the following calculating and storing a series of ambiguous angle error measurement values obtained from receiving amplitude values of a radioelectric signal coming from an emitting source on said first and second receiving channels, each angle error measurement value being representative of a ratio between receiving amplitude values on said first and second receiving channels, and corresponding to an angular deviation relative to a reference angular value; calculating a convolution function on said angular range tween said series of ambiguous angle error measurement values and a series of theoretical angle error measurement values of said receiving channels previously calculated and stored, determining an angle of arrival of said received radioelectric signal as a function of an estimate of a maximum of said calculated convolution function.

摘要： A bearing measuring system for determining the direction of arrival of a wave by rotating directional antennas or a goniometer to which the directional antennas are connected or rotating the directivity of such directional antennas or goniometer by electric means. The receiver of bearing measuring system of the type disclosed is usually constructed to determine the bearing of an amplitude modulated wave while confirming information about arriving waves. With a single receiver for frequency modulated waves it has been difficult to determine the bearing from adding the outputs of the directional antennas and the output of a nondirectional antenna while confirming information about arriving waves. With the system according to the present invention, it is possible with a single receiver to determine the bearing of the aforementioned frequency modulated waves while confirming information about the waves.
