  8. This dissertation discuss the key technology of wide band digital t / r module, including : architecture of the wide band digital t / r module ; wide band signal generating technology based on ddws ; using fiber technology to transmit data between radar center and t / r moudle. after studying the digtal t / r module technology over the world, this dissertation present a scheme of l band ( 1300mhz ) wide band ( b = 100mhz ) digital t / r module, and design a test board to verify transmitting technology of wide band digital t / r module, it works at l band. it use gigabit fiber components to transmit data between radar center and t / r module, use ddws and quadrature modulate technology to generate wide band radar transmitting signal, all control signal is generated by fpga

    本文探討了寬帶數字t / r組件發射通道的關鍵技術，主要包括:數字t / r組件的體系結構、基於ddws技術的寬帶信號的產生以及數字t / r組件收發數據的光傳輸技術。本文在深入研究了國內外數字t / r組件技術的基礎上，提出了一種l波段（ 1300mhz ）寬帶（ b = 100mhz ）數字t / r組件的原理框圖，並且設計了試驗板來驗證寬帶數字t / r組件發射通道技術。該試驗板採用千兆比特光纖技術實現寬帶數字t / r組件與雷達主機的數據傳輸，採用ddws加正交調制技術產生寬帶雷達信號，採用一片fpga完成整個組件的控制。
