dc.description.abstract | Compact and low-cost reflection-mode active imagers with a high angular resolution that can form images through a variety of obstacles and operate in visually impaired conditions are needed in industrial, security and safety applications [1]. Achieving a sub- 1 ° angular resolution using 79GHz CMOS radar imagers, which is far off from 0.1 ° for lidars, requires an aperture larger than 600cm2. This paper reports a 430GHz 1×3 CMOS concurrent transceiver (TRX) pixel array that is used with a 6cm diameter Cassegrain-type folded-path reflector (area = 28cm2) to form images of objects in heavy fog around 3m away with an angular resolution of 0.7°. The pixel integrates an antenna, a transmitter, a coherent receiver, an LO generation and synchronization circuits in an area close to (lambda/2)2 at 430GHz [3], [4]. The pixel achieves a minimum DSB noise figure (NF_DSB) of 39dB and the 1×3 pixel array exhibits a measured peak effective isotropic radiated power (EIRP) of -4dBm at DC power consumption of 85.8mW for the 3 pixels. Compared to the state-of-the-art concurrent TRX pixel operating at 430GHz [3], the new pixel achieves 15dB lower NF_DSB. This work demonstrates reflection-mode imaging using a concurrent TRX pixel array without the aid of optics in the signal transmission and reflection paths. These pixels can be used to form a focal-plane array (FPA) for an increased field of view (FoV) with orders of magnitude lower power consumption compared to that of phased arrays at a given angular resolution. © 2022 IEEE. | - |
