24 GHz 頻率調變連續波雷達系統之前端電路設計與整合

Abstract

本論文研製一個24 GHz頻率調變連續波雷達系統的前端電路，適合於車輛防撞機制。24 GHz頻率調變連續波雷達前端電路，包括6 GHz壓控振盪器、倍頻器、放大器、低雜訊放大器。最後加入原有的電路進行整合及量測，使得雷達的偵測，能夠達到40公尺以上的能力。

A front-end circuit of 24 GHz FMCW Radar system has been developed in this thesis. It is applied in the vehicle anti-collision mechanism. This FMCW Radar consists of the 6 GHz voltage control oscillator (VCO), the frequency doubler, the power amplifier, the 24 GHz low noise amplifier (LNA). Finally, we integrated the RF circuits to measure and make sure the radar detection ability can be achieved to 40 meters.
