Hybrid Sensor for Detection of Objects Using Radio Tomography

The article presents a solution for image reconstruction using radio-frequency tomography. The system is based on measuring the strength of the radio signal between the transmitter and the receiver. In the case where the object is measured between the transmitter and the receiver, the value of the signal strength changes as a result of reflection, absorption or dispersion of electromagnetic waves. The application can determine the position using multiple Wi-Fi signal sources.
