FPGA-based Airborne Encoding and Decoding Module of the Pulse Distance Measurement System Design and Implementation

According to the principle of a certain type aircraft decimeter wave instrument landing system, It provides a FPGA-based design encoding and decoding module of airborne ranging module. The program achieved the basic functions of the original simulation system by discrete components constitute, which use FPGA chips with 3 million gates. So accuracy greatly improved, and this program has strong design flexibility and scalability. Actual measurement and simulation shows that the program can meet the design function, the operation is stable and reliable.
