典型的UWB FMCW地面穿透（GPR）雷达在低频下操作，这需要宽的扫描带宽，因此需要复杂的架构和笨重的宽带天线。这对系统的便携性提出了独特的挑战，特别是对于手动，广域户外测量。在本文中，我们提出了第一个设计，制造和表征的一个完整的共形和小型化的雷达系统被卷起在一个“海报一样”的容器，使用增材印刷技术。由于集总或分布式无源器件、有源器件和Rx/Tx天线可以共享同一柔性基板，因此所提出的雷达技术被认为是单片的。所提出的概念验证系统执行FMCW雷达的最基本操作，包括信号生成，以及用于GPR频率的LO和RF信号的放大和相关。具体来说，本文概述了柔性/共形单片雷达系统的超低成本系统集成、封装和实验验证，该系统对于不同程度的弯曲具有几乎相同的性能。
Typical UWB FMCW Ground Penetrating (GPR) Radars operate at low frequencies that require a wide sweep bandwidth thus necessitating complex architectures and bulky broad-band antennas. This poses unique challenges to the system portability especially for manual, wide-area outdoor measurements. In this paper, we present the first design, fabrication and characterization of a complete conformal and miniaturized radar system to be rolled up in a “poster-like” container using additive printing technology. As the lumped or distributed passives, the active devices and the Rx/Tx antennas may share the same flexible substrate, the proposed radar technology is considered to be monolithic. The presented proof-of-concept system performs the most fundamental operations of the FMCW radar including signal generation, as well as the amplification and correlation of the LO and RF signals for GPR frequencies. Specifically, this paper outlines an ultra low cost system integration, packaging and experimental verification of a flexible/conformal monolithic radar system with almost identical performance for different degrees of flexing.
