    • In certain exemplary embodiments, register banks are used to allow for fast beam switching (FBS) in a phased array system. Specifically, each beam forming channel is associated with a register bank containing M register sets for configuring such things as gain/amplitude and phase parameters of the beam forming channel. The register banks for all beam forming channels can be pre-programmed and then fast beam switching circuitry allows all beam forming channels across the array to be switched to use the same register set from its corresponding register bank at substantially the same time, thereby allowing the phased array system to be quickly switched between various beam patterns and orientations. Additionally or alternatively, active power control circuitry may be used to control the amount of electrical power provided to or consumed by one or more individual beam forming channels such as to reduce DC power consumption of the array and/or to selectively change the effective directivity of the array.
    • 在某些示例性实施例中,寄存器组被用于允许相控阵列系统中的快速波束切换(FBS)。 具体而言,每个波束成形信道与包含M个寄存器组的寄存器组相关联,用于配置波束成形信道的增益/幅度和相位参数等。 所有波束形成通道的寄存器组可以被预先编程,然后快速波束切换电路允许阵列上的所有波束形成通道被切换到基本上同时使用来自其相应寄存器组的相同寄存器组, 相控阵系统可在各种光束模式和方向之间快速切换。 附加地或可替代地,有源功率控制电路可以用于控制提供给一个或多个单独波束成形信道或由一个或多个单独波束成形信道消耗的电功率量,以便减少阵列的DC功率消耗和/或选择性地改变有效方向性 数组。

    • An active electronic steered antenna (AESA) circuit monitors bursts of a phased array that has a plurality of signal chains. Each signal chain therefore has a burst output for transmitting at least one burst. To monitor bursts, the AESA circuit has an input that is operably couplable with the burst output of at least one signal chain of the phased array. The input is configured to receive one or more bursts transmitted by the burst output(s) of the at least one signal chain. The AESA circuit also has a sample circuit operably coupled with the input and configured to sample the one or more bursts to produce one or more corresponding samples, and memory operably coupled with the sample circuit. The memory receives and stores the one or more samples. To provide access to the samples, the AESA circuit also has a memory interface.
    • 有源电子控制天线(AESA)电路监视具有多个信号链的相控阵列的突发。 因此每个信号链具有用于传输至少一个突发的突发输出。 为了监视突发,AESA电路具有可操作地与相控阵列的至少一个信号链的突发输出耦合的输入。 输入被配置为接收由至少一个信号链的突发输出发送的一个或多个突发。 AESA电路还具有与输入端可操作地耦合并且被配置为对一个或多个突发进行采样以产生一个或多个对应采样的采样电路,以及可操作地与采样电路耦合的存储器。 存储器接收并存储一个或多个样本。 为了提供对样本的访问,AESA电路还具有存储器接口。
