Abstract :
Linearity of VCO directly impacts on the range resolution of LFMCW radar. So, linearity correction is usually adoptted in practical applications. Because VCO´s linearity correction is a highly nonlinearity controlled object, which modern control method is effective with difficulty. Therefor, a system of linearity correction based on fuzzy control is proposed in this paper. The simulation results show that fuzzy controller performed well in linearity correction of VCO.
