Abstract

Microstrip arrays of GaAs antenna-coupled Schott­ky barrier diodes for millimeter wave imaging systems were developed. A method for estimating the imaging properties of such arrays in videosystems with Fuko test objects and ar­rangement for forming the monochromatic spatial incoherent radiation is suggested. Circular asymmetry of modulation transfer function of the receiving elements was experimentally revealed. It seems to be inherent to the majority of such kind of the arrays. This asymmetry is ought to be taken into account during the development of imaging systems on the basis of these arrays.
