Arrangements and directions of investigations for application of polarization microwave imaging of different objects in millimeter wave range for purpose of object recognition, emergency management, security control, etc. are discussed. Preliminary experimental results in dual polarization imaging at frequency 94 GHz are presented. Possibilities to increase spatial resolution of the microwave images on the base of a priori information about spatial spectrum of investigated objects are discussed. Methods of object recognition from polarimetric microwave stereo images are under consideration.
