Abstract: Non-linear junction detectors (NLJD) are used for detecting objects which contain p-n junction or corrosive materials (m-m junction) in a target area. p-njunctions are mostly included in electronic circuits which may contain diodes, transistors, amplifiers etc. Typical NLJDs employ harmonic radar principels where the 2(nd) and 3(rd) harmonics created by the target area after illimunation by a sinusoidal signal are compared to distinguish whether a p-n or m-m junction or nothing at all exists in the area. In general, the p-n junctions create stronger 2(nd) harmonics than the m-m junctions do. The performance of NLJD is measured over how well it can differentiate p-n and m-m junctions. In this paper, we investiagted the factors that effect the NLJD performance. It is observed that the single tone illuminater signal has inferior performance. Therefore, we investigated a 2-tone illuminator signal and analyzed the impact of additoal harmoncis created by the combination of sums and differences of the two illuminating tones.
