摘要

介绍了一种采用均匀线性相控阵接收的自适应数字波束形成单脉冲雷达系统。数字波束形成由天线元件(阵列)、接收器模块、模数转换器和控制器组成。这些自适应雷达系统已经成功地应用于处理实验相控阵天线测量数据的实际任务中。这些天线遵循经典的“数字波束成形”模型，因为我们可以在每个天线单元中获得接收信号的数字化幅度和相位。在接收方式上，自适应雷达系统的主要优点是改进的快速自适应方向图消零、天线自定标、超低副瓣和自适应时空处理。

Adaptive interference cancellation

An adaptive digital beamforming monopulse radar system that uses a uniform linear phased array in the receive mode is described. Digital beamforming consists of antenna elements (array), receiver modules, analog-to-digital converters and a controller. These adaptive radar systems have been successfully applied to the practical tasks of processing measured data from the experimental phased-array antennas. These antennas follow the classic "digital beamforming" model since we have available the digitized amplitude and phase of the received signal at every antenna element. In receive mode the main advantages of adaptive radar systems are improved fast adaptive pattern nulling, antenna self-calibration, ultra-low sidelobes and adaptive space-time processing.
