So what we're doing right now with our observational technique, the Dopplertechnique, is taking really the very first steps to finding Earth-like planets.
因此我们利用现有的观测技术——多普勒技术所做的研究正是找到类地行星的最初几步。

Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.
On the bases of analyzing triangle wave form modulated LFM, the method of using DDR (Dual Channel Directional Doppler range) technique to eliminate the influence of speed to range is presented.
