Under the different laser parameters, the electron energy gain depends on the laser intensity, focal spot size and pulse width.
不同激光参鼍条件下，得到了电子的能量增益与激光强度、焦斑大小和脉冲宽度关系。
The conclusion shows that reasonable selections of the focal distances of the main reflector may be able to obtain low RCS, keeping the high-gain under the antenna unchanged.
结果表明，在保持增益不变的情况下合理选择主反射面的焦距是能够达到降低雷达散射截面的需要的。
There are no evident energy gain when the focal spot size is too big or small.
电子的能量增益有一个最佳焦斑大小。
