Radar-based occupancy sensors have a potential to provide an effective tool for building occupancy monitoring, without privacy concerns inherent to camera use. In this paper we propose an occupant count approach based on spectral features of continuous wave Doppler radar signals in the presence of multiple occupants. The proposed approach is tested using envelope-transient simulation for the case of ten occupants, and it is demonstrated that spectral features change proportionally to the number of occupants.}, organization = {This work was supported in part by the National Science Foundation (NSF) under grants IIS 1915738, and CNS2039089, the Fulbright Scholar Program, and the Spanish Ministry of Science and Innovation (MCIN/AEI /10.13039/501100011033) under grant PID2020-116569RB-C31.}, publisher = {Institute of Electrical and Electronics Engineers Inc.}, publisher = {2nd International Microwave and Antenna Symposium (IMAS), Marrakech, 2024, 140-143}, title = {Continuous wave doppler radar occupant count estimation using spectral features}, author = {Ramírez Terán, Franco Ariel and Suárez Rodríguez, Almudena and Boric-Lubecke, Olga and Lubecke, Victor}, }
