Effects of image formation, sampling and reconstruction in focal plane antenna array (FPAA) MMW/SMMW imager are analyzed in terms of its spatial frequency response. Rigorous expression for the optical transfer function (OTF) of an imaging subsystem of the imager is derived. Formalism of average modulation transfer functions (MTF) for sampled imaging systems is extended for exact MTF analysis of both the entire FPAA MMW imager and its constituent subsystems.
