Abstract

This paper presents the new development result of the multi-band, the multi-mode SDR(Software Defined Radar) platform. The SDR hardware platform is implemented by using the reconfigurable multi-band RF transceiver and antenna modules of S, X, and K-bands, and a programmable signal processing module. The SDR software platform is implemented by using the multi-mode waveform generation of CW, Pulse, FMCW, and LFM Chirp as well as the adaptable algorithm library of signal processing and open API software modules. Through the integrated test of the SDR platform, the operational performance was verified in real-time. Also, through the field-application test, the ground target and air-vehicle drone target were successfully detected and their test results were presented.

본 논문은 다중대역 및 다중모드의 레이다 기능을 갖는 새로운 SDR(Software Defined Radar) 플랫폼의 개발 결과를 제시한다. SDR 하드웨어 플랫폼은 다중대역의 S, X, 그리고 K 밴드의 교체 가능한 RF 송수신기 및 안테나 모듈과 프로그램 가능한 신호처리기 모듈로 구현된다. 소프트웨어 플랫폼은 다중모드의 CW, Pulse, FMCW, LFM Chirp 파형 발생과 적응 가능한 신호처리 알고리즘 라이브러리 모듈 및 개방형 API 소프트웨어 모듈로 구현된다. SDR 플랫폼의 레이다 통합시험을 통하여 동작 성능을 실시간으로 검증하였으며, 또한 현장 활용시험을 통하여 지상 표적 및 비행체 드론 표적을 성공적으로 탐지하여 시험 결과를 제시하였다.
