| 为充分发挥C频段舰载雷达在海上蒸发波导条件下的目标探测能力,开展了雷达天线架设高度
的研究。根据基于抛物方程（PE）的电磁波传播衰减计算方法，计算并比较了C频段舰载雷
达辐射电磁波在不同蒸发波导高度条件下的传播衰减值，根据结果建议在蒸发波导高度普遍
较高的南海，天线架高定在10 m左右，在蒸发波导高度一般不超过15 m的黄海海区，天线架
高定在20～30 m之间，实际应用中需考虑雷达使用海区的蒸发波导高度分布规律。研究结果
对于C频段舰载雷达的设计和使用具有参考价值。 |

| Abstract: |
| In order to achieve optimum target detection performance of C-band shipboard ra
dar, the choice of radar antenna height is researched. With the method of calcul
ation of electromagnetic propagation loss based on PE(Parabolic Equation), the
propagation loss of C-band shipboard radar in different height evaporation duct
conditions is calculated and compared. The conclusion suggests that, the best h
eight of the antenna should be 10m on the South China Sea where the duct he
ight is much higher, but on the Yellow Sea area where the evaporation duct heigh
t is often not over 15 m, the best antenna height should be between 20 m and 30
m. Applying the conclusion should make accordance with the distribution characte
ristics of sea evaporation duct based on the history hydrology records of sea ar
eas. The conclusion drawn will be useful for design and operation of C-band shi
pboard radar in different evaporation duct conditions. |
