Paper Abstract

Millimeter-wave imaging has expanded from the single-pixel swept imagers developed in the 1960s to large field-ofview real-time systems in use today. Trex Enterprises has been developing millimeter-wave imagers since 1991 for aviation and security applications, as well as millimeter-wave communications devices. As MMIC device development was stretching into the MMW band in the 1990s, Trex developed novel imaging architectures to create 2-D staring systems with large pixel counts and no moving parts while using a minimal number of devices. Trex also contributed to the device development in amplifiers, switches, and detectors to enable the next generation of passive MMW imaging systems. The architectures and devices developed continue to be employed in security imagers, radar, and radios produced by Trex. This paper reviews the development of the initial real-time MMW imagers and associated devices by Trex Enterprises from the 1990s through the 2000s. The devices include W-band MMIC amplifiers, switches, and detector didoes, and MMW circuit boards and optical processors. The imaging systems discussed include two different real-time passive MMW imagers flown on helicopters and a MMW radar system, as well as implementation of the devices and architectures in simpler stand-off and gateway security imagers.
