                      某相控陣天線抗太陽輻射熱設計及研究

                      摘要天線作為雷達信號接收與發射的裝置,常常暴露在強烈太陽光輻射之下,太陽光的熱效應會使天線罩內部模塊工作溫度過高,引起天線內部模塊過熱失效,嚴重影響天線的各項指標性能。針對某相控陣天線進行抗太陽輻射熱設計,通過對天線進行熱仿真,結合縮比模型試驗與研究,解決了該相控陣天線因太陽輻射熱引起的問題。

                      AbstractAs the signal transmit/receive module of radar, antenna is often exposed to the intense solar radiation. The high temperature of the radome inner module caused by the thermal effect of sunlight can make antenna inner module to be overheating and failure,the performance index of antenna will be severely influenced. This paper is aimed at the thermal design of phased array antenna caused by solar radiation,the problem of circuit damage due to solar radiation thermal was solved by simulation combined with scaled model testing and research.
