摘要

本文讨论了一种用于慢速运动目标探测的调频连续波雷达多普勒的设计和性能。将其建模为一种低成本、可行的用于测量特定运动目标距离和速度的雷达遥感器。工作在ISM频段，中心频率为2.4GHz，发射功率约为11.3dBm，发射信号带宽为52MHz。雷达也采用线性调频波形、双基地天线系统和多普勒模式操作。该雷达硬件架构是通过组装现成的电子设备构建的，并在微波实验室中对慢速运动目标进行了测试。用于评估和分析雷达性能的目标是一个随时间以不同速度移动的人体。分析表明，该雷达系统具有探测和测量目标速度和距离的能力。此外，该雷达系统对近程运动目标的最小测速可达0.77 m/s。

FMCW Radar for Slow Moving Target Detection: Design and Performance Analysis

This paper discusses the design and performance of a Frequency Modulated Continuous Wave (FMCW) Radar Doppler for slow moving target detection. It is modeled as a lowcost and feasible radar remote sensor for measuring particular moving target's range and velocity. It operates at ISM band with a center frequency of 2.4GHz, transmit power of approximately 11.3dBm and 52MHz transmit signal bandwidth. The radar also employs linear FM waveform, bistatic antenna system, and Doppler mode operation. The radar hardware architecture is built by assembling off-shelf electronic devices and tested towards slow moving target in a Microwave Laboratory. The target that is used to evaluate and analyze the radar performance is a human body which moves at different speeds over time. The analysis demonstrates that the proposed radar system capable of detecting and measuring the target's velocity and range. Besides, the radar system demonstrates that it can measure min velocity of 0.77 m/s for the short range moving target.
