Digital Generation and Phasing of Transmitter Signals for SuperDARN Class
نویسندگان
چکیده
It is planned that the TIGER N.Z. radar will be a digital evolution of the current analog system, where the phasing matrix for both transmitter and receiver arrays, and the receiver architecture will be implemented in Field Programmable Gate Array (FPGA) technology. Producing a fully digital system in FPGA technology allows a different solution to the current analog approach. An added challenge is the utilization of the DSP techniques such as multirate filters to enhance the performance of the implementation. In this paper we discuss our proposal for a digital SuperDARN radar. Our initial investigations are presented, which we believe not only demonstrate that the concept is feasible, but that a digital radar will provide many benefits to the SuperDARN community.
