Embodiment
[0048] Please see first figure 1 , figure 1 It is a schematic diagram of the composition of the integrated digital intermediate frequency receiving system of TCAS and S-mode transponder of the present invention, mainly including four-way parallel processing digital down-conversion module, TCAS baseband preprocessing module and S-mode transponder baseband preprocessing module.
[0049] The process of separating and extracting effective C-mode response signal, S-mode response signal, A / C-mode inquiry signal and S-mode inquiry signal is mainly completed by the following steps:
[0050] Step 1: Digital down-conversion. Use Altera's StratixIII series FPGA to down-convert the under-sampled digital intermediate frequency signal (20MHz);
[0051] Step 2: The TCAS processing channel is separated from the Mode S transponder processing channel. Use the signal line set by the radio frequency, antenna receiving channel and other information to determine which channel should be responsib...
