Abstract:

Effective transmission and distribution of tactical information with reference to remote control and telemetry, orientation/navigation, and battlefield intelligence are crucial to sharing tactical information. The tactical data links relaying and multiplexing system is applied widely in information warfare to save channel resource and reduce the complexity of modulation and demodulation. In correspondence with the requirements that airborne equipment should be small, light, and low power consumption while is capable of transmitting information effectively, this paper presents a new method for FPGA based data multiplexing relay transmission of air tactical data links. The hardware programming algorithm and architecture are optimized upon a single FPGA chip, taking up fewer chip resources; the pipelining is designed to be fully parallel to fulfill the requirements of high-speed real time processing of tactical information; the design inside FPGA is modularized being open and flexible for the system to be reconfigured and upgraded easily. The simulation demonstrates that the module can integrate tactical data streams with various types and rates into one high-speed data stream effectively.
