脉冲雷达测距系统
摘要：
在脉冲雷达测距系统中，定向耦合装置被设计用于将通过天线(8)发射的发射脉冲(TX)传送至目标(9)以及用于将通过天线(8)接收的目标反射信号(RX)传送至信号混合器(10)，该信号混合器生成中频信号。为了在目标测量中植入标准测量，该定向耦合装置(6)包括四端口环行器，该环行器具有设置在用于接收发射脉冲(TX)的端口(6a)和耦合连接至天线(8)的端口(6c)之间的附加端口(6b)。基线(7)连接至所述附加端口(6b)，用于生成相应输入脉冲的参考回波脉冲(RX′)。环行器(6)被设计用于分离发射脉冲(TX)的一部分(TX′)至基线(7)并将参考回波脉冲(RX′)传送至天线(8)。
摘要（英）：

In a pulse radar ranging system, a directional coupling device is designed for transmitting the transmitted pulse (TX) transmitted through the antenna (8) to a target (9) and transmitting the target reflection signal (RX) received through the antenna (8) to a signal mixer (10) that generates an intermediate frequency signal. For implanting a standard measurement in the target measurement, a directional coupling device (6) comprises a four-port circulator which is provided with an additional port (6b) that is provided between a port (6a) used for receiving the transmitted pulse (TX) and a port(6c) that is coupled and connected to the antenna (8). A base line (7) is connected with the additional port (6b) for generating a reference echo pulse (RX') corresponding to the input pulse. The circulator (6) is designed for separating one part (TX') of the transmitted pulse (TX) to a baseline (7) and transmitting the reference echo pulse (RX') to the antenna (8).
