Paper Abstract

The spatial resolution of millimeter wave (MMW), submillimeter wave (SMMW) and infrared (IR) quasi-optical imagers based on the usage of focal plane antenna arrays (FPAA) is limited by several common factors. Analytical expressions for the point spread functions (PSF) of FPAA imagers are derived for both coherent and spatially incoherent imaging. The possibility of developing advanced super-resolution imaging algorithms using PSFs determined to a high accuracy is discussed.
