仰角扫描能量有效分配对机相扫体制相控阵雷达的设计十分重要。在工程设计中，需针对不同的工作环境和工作模式，采用灵活的能量分配模式。能量分配牵涉到雷达系统的各种重要参数如发射机峰值功率、最大发射脉宽、天线增益、天线转速、波束宽度、仰角覆盖范围、最大高度覆盖、最大作用距离等。文中提出了仰角扫描能量时问的优化分配原则和方法，使雷达的能量和时间在帧时间内分配达到性能最佳，这种方法已在多部相控阵雷达设计中采用。

It is very important for mechanism-phase scanning phased array radar to effective distribute energy and time in elevation.In engineering project work,flexible distributing energy mode should be selected in difference operating condition and operating mode.Energy distribution involves many radar's parameters,such as peak power of transmitter,maximum pulse width,antenna gain,rotating speed of antenna,beam width,covering range of elevation,maximum height and range and so on.This paper proposes principle and method of optimizing energy and time distribution in elevation to obtain good performance in the frame time,and this method has been used in engineering project of several phased array radars.
