초록

추적 레이다 시스템은 레이다 신호를 송신하여 표적을 맞고 돌아오는 아주 미약한 신호를 획득하여 추적하는 시스템으로 신호처리기에서 신호를 획득 및 처리할 때 공급되는 전원의 잡음 수준이 매우 중요하다. 또한 빠른 시간에 레이다 신호를 처리하기 위해서는 고속의 전처리를 위한 FPGA와 실시간 알고리듬 수행을 위한 멀티코어 DSP의 적용이 필수적이다. ADC, FPGA와 DSP 설계를 위해서는 각각이 요구하는 전원에 대한 설계 또한 매우 중요하다. 본 논문에서는 레이다 신호처리를 위한 ADC, FPGA 및 DSP로 구성되는 신호처리기의 최적의 전원 설계에 대하여 설명한다. 각 부품이 원하는 전원에 대하여 어떠한 부품을 적용하여 설계를 하는지 상세히 설명한다. 최종 설계된 회로카드를 제시한다.

The tracking radar system is a system that transmits a radar signal to acquire and track a very weak signal that hits the target and returns. In addition, it is essential to apply the FPGA for high-speed preprocessing and the multi-core DSP for real-time algorithm performance to process radar signals in a short time. For the ADC, FPGA, and DSP design, the design of the power required by each is also very important. This paper describes the optimal power design of the signal processor consisting of ADC, FPGA, and DSP for radar signal processing. It explains in detail what parts are applied to each component to design the desired power. We present the finally designed circuit board.
