摘要
调频连续波雷达(FMCW)的性能与压控振荡器(VCO)的调频线性度密切相关。通过提出VCO非线性问题,说明VCO的调频线性度对FMCW性能的影响,给出一种基于FPGA和DAC的VCO非线性矫正方法,对其矫正性能进行仿真验证,并且在Ka波段FMCW雷达平台上进行了实测验证,效果良好。
The performance of the frequency- modulated continuous wave radar （FMCW） is related to the linearity of voltage - controlled oscillator （VCO） . The actual VCO nonlinear problems degrade performance of FMCW. In this paper, one VCO nonlinear correction method based on the FPGA and the DAC is given. Later, it shows the simulation performance of this method of correction and experimental verification in the Ka - band FMCW radar platform. The result shows that the method discussed in this paper has good results.
