Millimeter wave imaging technology makes possible imaging of phenomena, which are inaccessible to visible light, but suffer from speckles, produced by coherent sources. We report a 50\% speckle reduction, measured with a free-space vector network analyzer over the full W-band. Our experiments demonstrate how Hadamard mask operates as a tunable filter.
