MODULARIZED ULTRA-WIDEBAND PHASED ARRAY WITH INTEGRATED SENSING AND LOCALIZATION

VAlue proposition

Wireless techniques are increasingly popular to serve perception tasks such as localization and sensing due to their ubiquity, robustness to adverse light condition, and privacy preserving features. However, the diverse application scenarios impose highly different requirements for spatial resolution of the perception, the capability to serve different types of users (such as users carrying devices and device-free subjects), as well as various constraints on the cost and form factors of the radios. A one-size-fits-all wireless radio or array layout rarely works.

Description of Technology

Our technology is a modularized ultra-wideband phased array to facilitate the adaptability of wireless perception techniques to diverse scenarios. This technology uses an array using the low-cost, commercial-off-the-self UWB radio with a single radiofrequency (RF). The system is configurable into different layouts according to the needs of a specific application, requiring zero hardware redesign. The design provides the capability of joint localization and sensing. The technical merits include (1) novel signal processing methods that eliminate random phase noises among independent radios; (2) 3D localization and radar data processing pipeline; (3) user-friendly module design and software toolchains that make it convenient for users to customize their array.
