摘要： A phased array antenna includes a plurality of first antenna elements and a plurality of phase shifters respectively connected to the first antenna elements. An amplitude and a phase of each of the antenna elements are determined by a method of opposing a pick-up antenna at a distance from the phased array antenna to measure a composite power of the phased array antenna while changing phases of the phase shifters for determining the ratio of the maximum power to the minimum power, and the phase value for the maximum power, from which the amplitude and phase are computed. A second antenna element is incorporated in the phased array antenna as a pick-up antenna to measure with mutual coupling an amplitude and a phase of each antenna element by the method and to determine differences in amplitude and phase between the opposed pick-up antenna and the second antenna element so that an amplitude and a phase subsequently measured with the second antenna element are corrected with the differences in amplitude and phase to determine an amplitude and a phase of each antenna element.

摘要： An antenna system for transmitting radio waves in the same direction as the direction of arrival of incoming radio waves. The arrival direction is detected by a fast Fourier transform processor. The transmitting direction is adjusted by phase-shifting radio waves from a feeder on the basis of the detected arrival direction. Further, signals in the system are transmitted through optical fibers in order to decrease the processing time.

摘要： The present invention relates to an array antenna for receiving a signal in a microwave band. The array antenna includes a plurality radiating element arranged in subarrays, each subarray having a first feeder connected to the radiating elements and a low noise amplifier (LNA) connected to receive the output of the first feeder, a frequency converter, and a second feeder for combining the outputs of the sub arrays from the LNAs. According to this structure, in the formula representing the noise temperature observed at the radiating elements, the gain the LNA appears in the denominator in the term representing the loss of the second feeder which combines the outputs of the sub arrays. Therefore, if the gain of the LNA is sufficiently large, it is possible to disregard the influence of the loss of the first and second feeders for combining the outputs of the sub arrays on the noise temperature. If each sub array is composed of a plurality of radiating elements and a first feeder for combining the outputs of the radiating elements, the loss of the second feeder is reduced more as the number of sub arrays is increased. As a result, the gain over temperature (G/T) is enhanced. Since it is possible to set the optimum number of sub arrays, it is possible to realize the enhancement of the G/T at the minimum necessary cost.
