| Abstract: |
| The Mode S signal processor is the core part for data processing of the i
nterrogator/ transponder. In this paper,an implementation scheme based on FPGA f
or Mode S signa
l processing is proposed. For the signal′s modulation and format, the implement
ation of processing intermediate frequency(IF) signal, the synchronous detection
of
signal and the extraction of information are described. By analysing the encodin
g/ decoding principle of the Mode S interrogator/ transponder signal, the proces
sing flow and design details are introduced. The scheme has passed simulation te
sts
and also been verified in the actual engineering project. |
