摘要
好的系统设计可以大大降低大型雷达馈线系统的研制成本,大型地面雷达馈线系统中通常需要数量巨大的馈线器件,从减少系统互联和射频直流共用等方法可以解决高成本问题。减少系统中的连接器不仅可以大大降低系统的研制成本,也可以大大增加系统的可靠性。射频直流共用可以省去供电的大量电缆及其对应的接头。
Better system design will lead to lower cost of the large radar feed system. The feed system of the large ground radar is usu- ally made up of the huge number of feed units, and this will lead to the higher manufacture cost. For solving this problem, the way will be presented in this paper such as reducing the system connecter and feeding the microwave and direct current signal in one ca- ble. Reducing the connecter is beneficial to not only the lower system cost but also the higher system reliability. It can leave out a great lot of power supply cable and corresponding connecter that feed the microwave and direct current signal in one microwave cable.
