Super Resolution Radar/Imaging at mm-Wave frequencies
From iis-projects
Project Description
The spectrum at millimeter-wave (mm-Wave) and terahertz (THz) frequencies is seen as a crucial component in meeting the growing demand for data in densely populated urban areas and paving the way for the next wave of wireless technology. To counter the high path loss associated with mm-Wave/THz, highly directional antenna arrays have become common. Their widespread deployment will result in dense wireless sensor networks, which allow for joint communication and sensing. However, the effective use of high-directivity antenna arrays requires real-time precise localization between transmitters (TXs) and receivers (RXs) in dynamic mobile applications.
Phased arrays are essential to realize high array gains and enhance the communication distance. However, their pencil sharp beams require precise localization and tracking of wireless nodes to maintain beam alignment and reliable communication, especially in mobile wireless links. In parallel, array-based mm-Wave radars require large arrays for precise angular resolution that is fundamentally limited by the form factor and power consumption of the radar systems.
This project aims to explore the area of phased array systems to achieve super resolution radar systems and drive the theoretical approach of using phased array as a super radar system. Also, based on the candidate progress, the project will involve validation of his/her theoretical model through measurements and experiments at mm-Wave, which will be held on existing IPs.

- Get to know and use advanced RF/mm-Wave instruments.
