Abstract

In this work, we describe the construction of a radiometric based passive human detection system. Thermal radiations emitted by the human body in the microwave range are sensed by this system. The centre frequency of operation was chosen to be 3.7 GHz for easy penetration through obstacles and for avoiding radio-frequency interference. The system was designed and implemented using off-the-shelf components. The prototype's performance was evaluated with real-life experiments that were carried out with detection behind wooden doors as well as in front of the system. The results indicate that the system has the capability to detect the presence of a person up to a distance of 2 metres. © 2018 IEEE.
