In this paper,the definitions of the VCO tuning linearity are presented,the principle of sweeping nonlinearity correction is analyzed,and the latest developments of three basic sweeping nonlinearity correction technologies for VCO,including the reactance compensation,open loop and closed loop linearization schemes are discussed.
VCO扫频非线性校正技术是实现高精度及高分辨率线性调频连续波(LFMCW)雷达的关键技术之一。
6) the change of frequency
扫频特性
1.
The experimental results show that the circle patch probe is prior to open-ended coaxial line, both in sensitivity of reflection coefficient to the change of frequency and in radiation depth into tissues.
作者比较了终端开口同轴探头和圆形微带贴片探头的结构,并在纯水和1%盐溶液中分别测量了以上两种探头的扫频特性和场透入深度,实验表明,圆形微带贴片探头灵敏度和场透入深度优于改进前的终端开口的同轴探头,并有效降低了测量中的反射系数。
