【摘要】:针对复杂环境下测距的需求设计了一种基于ZigBee协议的无线FMCW雷达测距系统。采用DDS产生高精度三角波来调制FMCW雷达,中频信号经过滤波放大等处理后,再用DSP进行FFT和公式拟合法处理得出距离信息,并通过CC2530发送到上位机。经测试系统达到了设计要求。
[Abstract]:A wireless FMCW radar ranging system based on ZigBee protocol is designed to meet the needs of ranging in complex environment. The DDS is used to produce high precision triangle wave to modulate FMCW radar. After the intermediate frequency signal is processed by filtering and amplifying, the distance information is obtained by FFT and formula fitting with DSP, and sent to the upper computer through CC2530. The test system meets the design requirements.
