range gate

The scheme accomplishes range tracking by adopting three range gate tracking to make middle gate always centered at echo pulse center through feedback circuit and deviation calculation circuit.

该方案采用三波门跟踪，通过偏差计算电路和反馈控制电路使中间波门中心始终对准目标回波脉冲中心，完成距离跟踪。

In the experiment, the overflowing ability of gate, wing wall in the upstream and downstream of gate room, the rationality of plane distribution of diversion dike and protected bond range, and the rationality of distributing facilities for energy dissipation and erosion protection are studied.

试验对闸的过流能力、闸室上下游翼墙、导流堤的平面布置以及闸室上下游护砌范围的合理性、闸下消能防冲设施布置的合理性等进行了研究。
