Abstract
There has been interest in the possibility of detecting shorter lengths of linear conductor (20m and below) using transmitters of opportunity, similar to what has been previously examined for longer conductors at AM frequencies. A switch to a higher frequency, and therefore a shorter wavelength, should allow the shorter wire to absorb more of the radiated energy, and hence create a stronger reradiated field. The equipment used for this proof-of-concept demonstration was a software defined radio (SDR) which is capable of frequencies up to 1.8 GHz. This allows testing for not only AM and FM bands, but ultra-high frequency (UHF) and L-band frequencies. A series of tests were devised for measuring the reradiated fields. These tests were then conducted and the results are presented.
