Abstract

A high sensibility wideband millimeter wave receiver operating in Ka band on the background of imaging concealed objects is presented. The zero-bias direct detecting millimeter receiver achieves an effective bandwidth 9.2 GHz and NF <3.8 dB which can receive like noise signals that are typical for passive mm-wave imaging. The fundamentals of the system are described. The principle of operation, performance of the receiver and supporting measured date are described. Examples of images built with this receiver using a mechanically scanned system are presented proving its applicability for detecting concealed objects needs.
