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： A method and a system for locating ground equipment transmitting signals to a geostationary satellite, the method and the system being based on identifying the arrival directions of such signals within the coverage zone of the satellite. In the method, the arrival directions of the signals are identified by using a beam-forming active-module array antenna system on board the satellite, the system being controlled to define simultaneous beams in the radiation pattern of the antenna, the beams being superposed on one another with small offsets, the superposed beams corresponding to a limited analysis zone being illuminated within the coverage zone of the satellite, the system further being associated with a digital processing program which identifies the arrival directions of the signals which are received in the analysis zone.

摘要： A radiation source directs radiation toward a radiation sensor in such a way that the intensity of radiation sensed by the radiation sensor alternates in a periodic manner as the radiation source moves radially relative to the radiation sensor. The radiation sensor generates either a "1" or a "0" depending upon whether the intensity of the radiation sensed by the radiation sensor is above or below a particular reference value. Thus, the angular position of the radiation source relative to the radiation sensor is indicated by an alternating series of "1"s and "0"s. A multi-bit binary value which indicates the absolute position of the radiation source relative to the radiation sensor can be generated. In this case, a band of radiation is directed toward the radiation sensor. The radiation band is separated into a plurality of portions, the intensity of each successive portion being twice the frequency of the preceding portion. Each portion of the radiation band impinges upon a corresponding sensor. The signal generated by each sensor element is thus one bit of a multi-bit binary value which varies as the radiation source moves radially relative to the radiation sensor.
摘要翻译：辐射源以辐射传感器的方式将辐射引向辐射传感器，使得当辐射源相对于辐射传感器径向地移动时，辐射传感器感测到的辐射强度以周期性方式交替。辐射传感器根据辐射传感器感测到的辐射强度是高于还是低于特定参考值，产生“1”或“0”。因此，辐射源相对于辐射传感器的角度位置由“1”和“0”的交替系列表示。可以产生指示辐射源相对于辐射传感器的绝对位置的多位二进制值。在这种情况下，辐射带指向辐射传感器。辐射带被分成多个部分，每个连续部分的强度是前一部分的频率的两倍。辐射带的每个部分照射在相应的传感器上。因此，由每个传感器元件产生的信号是随着辐射源相对于辐射传感器径向移动而变化的多位二进制值的一位。

摘要： An omnidirectional receiver includes directional arrays for input signal directional arrays for input signal detection. The array signals are compared to determine which array has developed the greatest signal and its direction. The receiver is then stirred or switched to the identified directional array. After a delay to allow for steering, the input signal from the selected array is phase detected. Then after a second delay one of the phase detected signals is divided and replicated to determine the internal phase error and for phase comparison.

摘要： A lift truck (16) carries a leftwardly directed ultrasonic receiver (32L) and a rightwardly directed ultrasonic receiver (32R) and an RF transmitter (34). Upon depositing its load in an assigned bin in a warehouse (FIG. 1), a load sensor (22) is actuated to cause transmission of a coded signal as to lift height and vehicle identification to a central station (60). This initiates a vehicle search by energizing ultrasonic transmitters (42-52). The ultrasonic receivers (32L and 32R) on a vehicle in a path under surveillance detect the sonic signal and relay this to the central station by way of the RF transmitter (34). The time duration which elapsed from energization of the ultrasonic transmitter to detection of the sonic signal is used to measure vehicle path depth and a comparison of the magnitudes of the sonic signals received by the receivers (32L and 32R) indicates the heading direction of the vehicle.

摘要： A bearing detection system used in an Airborne Collision Avoidance System. The detection end of the system is formed as a directional antenna having 3 directional antenna elements extending radially at a 120.degree. angle with each other. The antenna element has an actual length corresponding to .lambda./8, wherein .lambda. is the wavelength of the receiving wave, but the element has an effective length corresponding to .lambda./4 by the provision of an impedance matching plate and a back lobe suppression plate. Bearings of the incoming wave can be detected by means of relative strength of the receiving signal levels of the three antenna elements obtained by amplitude comparison and by forming 3 bit truth table for six directions including the 3 directions of the antenna and 3 boundary directions thereof by the strength of the receiving signal received by the three antenna elements.
