Abstract

This paper proposes a FMCW radar transceiver with photonic elements. The proposed radar system is efficiently designed by budget analysis, and a wideband signal is generated using photonic elements. To verify the performance of the proposed radar system, field tests including changes in bandwidth are conducted. The results confirm that the resolution of ISAR images improves as the bandwidth increases as expected through the budget analysis.

摘要

本文提出了一种具有光子元件的调频连续波（FMCW）雷达收发机。通过预算分析对所提出的雷达系统进行了高效设计，并利用光子元件生成宽带信号。为验证所提出雷达系统的性能，进行了包括带宽变化在内的现场测试。结果证实，逆合成孔径雷达（ISAR）图像的分辨率随着带宽的增加而提高，正如通过预算分析所预期的那样。
