    • A system for estimating parameters of an incoming signal is provided. At least one antenna is coupled to at least one suitable receiver. The antenna(s) are spatially translated in an arbitrary trajectory. As the antenna(s) is being spatially translated, a data processing means samples the incoming signal at set intervals based on a clock signal provided by a system clock. By sampling the incoming signal at different times at different spatial locations on the arbitrary trajectory, the system acts as a synthetic antenna array. The different samplings of the incoming signal at different times and positions provide signal diversity gain as well as different readings which can be used to estimate and/or calculate various parameters of the incoming signal. The different samplings can be used to detect the incoming signal, estimate its angle of arrival, estimate its time of arrival, as well as other parameters.
    • 提供了一种用于估计输入信号的参数的系统。 至少一个天线耦合到至少一个合适的接收机。 天线在任意轨迹上空间转换。 当天线被空间转换时,数据处理装置基于由系统时钟提供的时钟信号以设定的时间间隔对输入信号进行采样。 通过在任意轨迹上的不同空间位置的不同时间采样输入信号,该系统充当合成天线阵列。 在不同时间和位置处的输入信号的不同采样提供信号分集增益以及可用于估计和/或计算输入信号的各种参数的不同读数。 不同的采样可用于检测输入信号,估计其到达角度,估计其到达时间以及其他参数。
