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
本文探讨了宽带数字t / r组件发射通道的关键技术,主要包括:数字t / r组件的体系结构、基于ddws技术的宽带信号的产生以及数字t / r组件收发数据的光传输技术。本文在深入研究了国内外数字t / r组件技术的基础上,提出了一种l波段( 1300mhz )宽带( b = 100mhz )数字t / r组件的原理框图,并且设计了试验板来验证宽带数字t / r组件发射通道技术。该试验板采用千兆比特光纤技术实现宽带数字t / r组件与雷达主机的数据传输,采用ddws加正交调制技术产生宽带雷达信号,采用一片fpga完成整个组件的控制。
