脉冲雷达装置及其操作方法
摘要：
提供了一种脉冲雷达装置，包括：TX单元，配置为根据单一TX时钟信号发射TX脉冲；多RX单元，配置为根据多个RX时钟信号接收通过许多RX天线所接收的回波脉冲；脉冲雷达驱动单元，配置为使用参考时钟信号生成所述单一TX时钟信号和所述多个RX时钟信号。该脉冲雷达驱动单元对于所述TX单元和所述多RX单元提供所述单一TX时钟信号和所述多个RX时钟信号。该脉冲雷达驱动单元调整作为所述多个RX时钟信号之间的延迟的RX时钟到时钟延迟，以便调整所述多RX单元的方向性，并且调整所述单一TX时钟信号和所述多个RX时钟信号之间的TX-到-RX延迟，以便调整检测范围。
摘要（英）：

Provided is a pulse radar device including: a TX unit configured to emit a TX pulse according to a single TX clock signal; multiple RX units configured to receive echo pulses received through a plurality of RX antennas according to multiple RX clock signals; and a pulse radar driving unit configured to generate the single TX clock signal and the multiple RX clock signals using a reference clock signal. The pulse radar driving unit provides the single TX clock signal and the multiple RX clock signals for the TX unit and the multiple-RX unit. The pulse radar driving unit adjusts an RX clock-to-clock delay that is the delay between the multiple RX clock signals so as to adjust a directivity of the multiple-RX unit, and a TX-to-RX delay between the single TX clock signal and the multiple RX clock signals so as to adjust a detection range.
