Abstract
In this paper is presented a new technique to improve the VCO linearity by resampling the measured IF signal in short-range frequency modulated continuous wave (FM/CW) radar based on a known reflecting reference, which caused intentionally by a specially fabricated paraboloidal antenna. The basic principle and special attention are given in following discussion. Moreover, a confirmed experiment in microwave non-reflective chamber is simulated. The result shows the feasibility of our self-made antenna and this method satisfactorily.
