The design of a highly integrated, miniaturized and highly reliable radar signal transmission network using the integrated integrated signal technology of complex signal transmission has been studied in this paper. It has the functions of radio frequency signal (14G-18G) power distribution and synthesis, wave control signal distribution and transmission, power distribution Features. At the same time, the EMI (electromagnetic interference) and SI (signal integrity) analysis and optimization of the network through radio frequency and digital signal co-simulation technology have significantly improved the easy resonance of the Ku-band broadband RF signal transmission network under complex electromagnetic environment. The control signal Reflection and crosstalk obvious phenomenon, improve the signal transmission quality, the measured results verify the simulation is accurate and effective. The design method elaborated in this article is the innovation of the traditional radar front technology, which is in line with the trend of high integration, miniaturization, complex electromagnetic environment and high reliability requirements of the modern radar front.
