This project involves using a software defined radio in creation of a harmonic radar system. A harmonic radar system works by sending out some type of stimulus signal to a harmonic reflecting tag. The tag takes in stimulus at a lower frequency and generates a second harmonic that is then re-radiated back out to a receiving system. The receiving system then processes and extracts information from it. The use of a software defined radio system allows for all kinds of information extraction through the use of baseband processing software. A few types of tags were created, a passive reflector tag, a digital modulation tag, and a analog audio tag. The analog audio tag was able to recover sound from a remote location passively and was the focus of the majority of the project testing.
