摘要： Curved sensor array configurations ( 702, Figures 1 A, 2A, 2B, 8A, 8B, 8C, 9, 10, 11) and methods (Figures 6A, 6B, 6C) of processing the data gathered by the sensors. A 2 dimensional embodiment (Figure 1 A) comprises singular ring of sensors that can monitor sources in a 2 dimensional plane. A sensor directly facing a target produces a maximum response (Figure 1 C). As the angle of a sensor relative to the target increases, the response decreases. Fitting the sensor response amplitudes.to a 2D Gaussian curve (Figure 1 B) and calculating the peak of the curve (606) allows a very accurate calculation of the angular direction (608) of the target. A 3D embodiment (Figures 2A, 8A, 8B, 8C) comprises sensors scattered over the surface of a sphere in order to monitor multiple targets in any spatial orientation. Again, the sensor amplitude data is fitted to a 3D curve or surface such as a Gaussian surface (Figure 2C). The present invention can resolve more than one target using deconvoluting techniques (622, Figures 4A, 4B, 4C, 5A, 5B, 5C, 5D).

摘要： An adaptive antenna apparatus is provided with a total of four or more, even number N of antennas including a plurality of pairs of antennas each having a bidirectional characteristic. The N antennas are provided respectively at vertexes of a polygon of the same number as the number N of the antennas, so that each pair of antennas of the plurality of pairs of antennas opposes to each other. An adaptive control circuit takes an adaptive control over radio signals using one pair of antennas opposing to each other among the N antennas. In the adaptive antenna apparatus, the each pair of antennas is provided to oppose to each other so that axes of directions of main beams of the directional characteristics of the each pair of antennas substantially coincide with each other.

摘要： Die an sich gleichen Hauptstrahlungskeulen zweier Peilantennen (1, 2) sind in der Peilebene winkelmässig so zueinander versetzt, dass sie sich überlappen. Im den Peilsektor bestimmenden Überlappungsbereich kann der Lagewinkel einer Mikrowellen-Signalquelle durch Pegelvergleich oder durch Quotientenbildung zweier mittels der Peilantennen (1, 2) empfangenen Signalspannungen festgestellt werden.
Im Nebenzipfelbereich aufgrund sich überlappender Seitenkeulen entstehende Fehlpeilungen oder Mehrdeutigkeiten werden dadurch vermieden, dass jeder Peilantenne (1, 2) ein Zusatzstrahler (13, 14) zugeordnet wird, dessen Hauptstrahlrichtung um einen bestimmten Winkel zur Peilantennenhauptstrahlrichtung in der Peilebene versetzt ist. Es wird dadurch der Strahlungspegel jeder der zwei Peilantennen (1, 2) bezüglich ihrer Hauptstrahlrichtung einseitig angehoben. Das Antennensystem nach der Anmeldung ist zum Einsatz in Funk-Aufklärungseinrichtungen geeignet.

摘要： A radio direction finding apparatus comprising an omnidirectional receiving element (21), an array of directional receiving elements (1.1-1.2N), two log video detectors (15, 16) suited for separate connection to two contiguous elements of said array and a subtraction circuit (27) for generating a signal containing the azimuth data of an r.f. transmitter.
In order to select echoes received through the main lobes of the two connected receiving elements from those received through the main lobe of the one element and a side lobe of the other element, the radio direction finding apparatus is provided with a threshold circuit (18) and two gate circuits (19, 20) separately inserted between the log video detectors (15, 16) and the subtraction circuit (27). The threshold circuit (18) passes the applied signals through the gate circuits (19, 20) if the strength of the latter signals exceeds that of the echo signal obtained from the omnidirectional receiving element (21) via a third log video detector (22).

摘要： A helmet-mounted tracker (404) and boresighting system (100) incorporated paired receivers on opposing sides of the helmet worn by the user (214) (e.g., left/right, top/bottom) that receive a directional signal (412, 414) from directional transmitters (104, 106) placed at fixed locations throughout the target environment (e.g., a mobile platform (102), multilevel structure (202), or simulated environment). Each paired antenna (112a, 112b, 114a, 114b) generates an RF signal based on the received directional signal (412, 414); the paired RF signals are summed to determine the current alignment of the helmet (and head) to the directional transmitter (104, 106). Alignment information may be used to calibrate or correct inherent drift of the inertial measurement unit (IMU) of the helmet-mounted head tracker (404).
