Abstract
It is shown that spatial variation in the temperature a periodically heated planar source causes partial spatial coherence of the near field of its microwave thermal radiation. This coherence can be revealed in the form of a peculiar interference pattern arising at a displacement of a diffraction grating along the source surface.
