新近发展起来的一种扫频型反射计,它使用双扫频信号源和带通滤波器时,能测量出同轴线或波导中各个反射点的距离和射的大小。给出了这种反射计的原理和在2GHz时得到的实验结果。
A newly developed sweep-type reflectometer that uses dual-sweep source and band-pass filters to measure distance and shot size of individual reflection points in a coaxial line or waveguide. The principle of this reflectometer and the experimental results obtained at 2 GHz are given.
