    • A method and a system are disclosed compensating for failed elements in an antenna array. The method assumes that at least the amplitude and, in most cases, the phase of, at least, some of the individual elements can be controlled to some extent. If one or more of the antenna array radiating elements are failed, at least some remaining elements are used to correct for this. The amplitude and phase radiation pattern of one of the failed elements is then synthesized using K of the remaining elements. The resulting excitation from this synthesis is superimposed on the failed array excitation at the positions of the K remaining elements. This procedure can be repeated for all the failed elements using the principle of superposition. A system utilizing the present method controls via a control unit a T/R module the phase and amplitude of each operating antenna array radiator.
    • 公开了一种补偿天线阵列中的故障元件的方法和系统。 该方法假设至少可以在一定程度上控制至少一些单个元件的振幅和大多数情况下的相位。 如果天线阵列辐射元件中的一个或多个发生故障,则使用至少一些剩余元件来校正这一点。 然后使用剩余元素的K合成一个故障元件的幅度和相位辐射图。 来自该合成的所得激发叠加在K个剩余元素的位置处的失效阵列激发上。 可以使用叠加原理对所有故障元素重复此过程。 使用本方法的系统通过控制单元控制T / R模块,每个操作天线阵列辐射器的相位和幅度。

    • An apparatus has an array of antennae. Each antenna in the array has a tile circuit including a frequency conversion circuit to generate from an incoming reference signal a local oscillator carrier signal operative as an outgoing reference signal for an adjacent tile circuit. A mixer receives the local oscillator carrier signal and combines it with an antenna signal to produce a frequency converted antenna signal. A matrix of phase shifters and variable gain elements produces a set of frequency converted and phase rotated antenna signals. Analog summers combine the frequency converted and phase rotated antenna signals with user input signals from the adjacent tile circuit for distributed analog beam forming of multiple streams. The user input signals correspond to distinct users tracked by the array of antennae.
