마이크로파 거리계의 VCO 비선형성에 의한 시스템 특성 분석 및 개선 방안 연구
Improved Design of the Microwave Level Meter upon VCO Nonlinearity
초록
In this paper, we have presented an improved design of the microwave level meter based on the principle of FM-CW radar. First, we have analyzed the effect of VCO nonlinearity on the spectral broadening of the beat signal, and presented a new type of design theory to linearize VCO tuning curve adopting FFT algorithm. Simulation results for a VCO having the linearity of 25% have been presented, which show the usefulness of the design algorithm.
