We experimentally resolve several weakly coupled nuclear spins in diamond\nusing a series of novelly designed dynamical decoupling controls. Some nuclear\nspin signals, hidden by decoherence under ordinary dynamical decoupling\ncontrols, are shifted forward in time domain to the coherence time range and\nthus rescued from the fate of being submerged by the noisy spin bath. In this\nway, more and remoter single nuclear spins are resolved. Additionally, the\nfield of detection can be continuously tuned on sub-nanoscale. This method\nextends the capacity of nanoscale magnetometry and may be applicable in other\nsystems for high-resolution noise spectroscopy.\n
