This paper describes a new radial velocity estimation method for the extended moving target of low signal-to-clutter ratio with the distributed space-borne SAR system. By velocity searching for one fitting best to the under-test signal, a fine estimation of target radial velocity can be achieved. The estimation performance would not be sacrificed in order to suppress clutter and/or interference and the high resolution radial velocity estimation can be achieved. A preliminary result against space-borne simulation data demonstrates the effectiveness of the proposed method.
