Dr. Lou Liangliang from the School of Electronics and Information Engineering published a high-level scientific research result entitled “Antenna as a Sensor: An Improved Vehicle Detection Solution Via the Use of Antenna Impedance and Magnetic Signature” in IEEE Transactions on Antennas and Propagation (IF: 5.7), which is one of the top journals of Chinese Academy of Sciences (CAS).

Existing smart parking systems (SPS) need parking status information to support their reliable and efficient operation. Magnetometer-based wireless parking sensors (WPS) have the advantages of low cost and easy installation, but the magnetic signal is susceptible to interference from neighboring vehicles. Taking the impedance characteristics of the antenna under the action of vehicles as the research entry point, this research result proposes an impedance and magnetometer-based parking detection (IMPD) solution, introduces the impedance characteristics of the antenna and its auxiliary radio-frequency (RF) circuits into the existing magnetometer-based parking detector, and constructs a strategy to improve the accuracy of the parking detection under the optimal condition of energy consumption. The related realization framework of this achievement is shown in the following figure.

Dr. Lou has published 7 high-level SCI papers in recent years theming on traffic parameter measurement for human-vehicle identification and parking space detection, 4 of which were published in CAS Zone 1 TOP journals.
