【摘要】 线性调频雷达在距离测量方面有着广泛的应用。本文介绍了一种利用X波段线性调频连续波雷达来探测高压线以防止吊车触电的技术。首先对线性调频雷达测距的原理作了简要分析,然后对雷达前端的硬件实现以及软件算法流程进行了较具体的描述,最后经过实际测试,验证了系统的稳定性和距离测量的准确性。更多还原

【Abstract】 Linear frequency modulation continuous wave( LFMCW) radar is widely used in range measurement. In order to prevent crane from electric shock,a power wires detection technology by using an X-band LFMCW radar is put forward. Ranging principle of chirp radar is analyzed briefly; hardware implementation of radar front-end and software algorithm flow are described in detail. Test results verified that the system features high stability and high ranging accuracy.更多还原
