Abstract

Frequency Modulated Continuous Wave radar or FMCW radar has obvious advantages on its low emitting power, strong resistance to inference signals, compact in size and high precision, therefore it is becoming widely used for distance and velocity measurement. The resolution of the FMCW radar is largely determined by the linearity of the Linear Frequency-Modulated (LFM) signal generated by the VCO, even if minor nonlinearity may lead to severe deterioration to the resolution of the system, accordingly the linearity of LFM signal is vital to the system overall performance. In real practice, however, the Voltage-Frequency curve of VCO more or less suffered from nonlinearity, so we must compensate its nonlinearity before a FMCW radar can be used.This paper compensate the nonlinearity of VCO operates on 60GHz wave band. We have designed a practical method, and implemented hardware experiments. Keywords-
