低频叶簇穿透雷达成像技术

低频叶簇穿透成像雷达工作于微波频率的低端，拥有远超传统窄带雷达的系统相对带宽，因此具备强的叶簇穿透和高分辨成像能力，经过近三十年来迅速发展，已在战场侦察、反恐维稳以及资源勘查与监测等领域有着广泛应用.文中分别从低频叶簇穿透合成孔径雷达（synthetic aperture radar，SAR）技术、低频叶簇穿透干涉SAR（interferometric SAR，InSAR）技术和低频叶簇穿透地面动目标指示（ground moving target indicator，GMTI）雷达技术三个具体应用，系统回顾了低频叶簇穿透雷达技术的兴起和研究现状，深入分析了各自的技术特点以及其中涉及的关键技术，最后探讨了低频叶簇穿透雷达技术的未来发展和新兴应用方向.

Low frequency foliage penetration radar imaging technology

The low frequency foliage penetration imaging radar works at the low end of the microwave frequency and has a wide relative bandwidth, compared with the traditional narrow-band radars. Therefore, it has strong foliage penetration and high-resolution imaging capabilities. It has been widely used in battlefield reconnaissance, counter-terrorism and stability maintenance, and resource exploration and monitoring. This paper introduces three specific applications: low-frequency foliage penetrating synthetic aperture radar (SAR) technology, low-frequency foliage penetrating interference SAR technology, and low-frequency foliage penetrating ground moving target indicator (GMTI) radar technology. It systematically reviews the rise and current research status of low-frequency foliage penetrating radar technology, analyzes their respective technical characteristics and key technologies involved, and finally discusses the future development and emerging of low-frequency foliage penetrating radar technology application.
