We experimentally study the dynamical response of weakly-interacting atomic matter waves to a periodically pulsed, disordered optical lattice potential consisting of two overlapping standing-waves of incommensurate spatial periodicity. For periodic driving with a single standing wave only, we observe behavior consistent with the kicked-rotor model, namely ballistic spreading of momentum wavepackets at quantum resonances, and dynamical localization otherwise. However, adding the second standing wave can greatly modify these two effects. In particular, we find that the addition of disorder destroys dynamical localization when the driving is off-resonant and suppresses delocalization for a resonant drive. Our findings directly relate to quantum localization phenomena in low-dimensional systems, and illustrate the role of decoherence in the dynamics of driven quantum systems.
