Study on Linearity Correction scheme for VCO Tuning Characteristics

摘要：

The linearity correction scheme for VCO tuning characteristics is the key to determine the performance of FMCW radar system. The paper introduces the basic definition of VCO tuning linearity. The linearity correction scheme for VCO tuning characteristics mainly indues three basic schemes, they are the reactance compensation, open loop and closed loop linearity correction scheme. Analyzing the basic principle of every correction scheme detailedly, and doing a key analysis of the closed loop digital correction scheme; Discussing their advantages and disadvantages, and introducing the latest research progress of VCO linearity correction schemes in detail.
