Intermodulation Radar for P-N Junction Detection

Intermodulation radar is a kind of harmonic radar. These radars not only receive the second and third harmonics but also intermodulation products of the transmitted multi-tone signal. These radars are useful for detection of non-linear electronics which are important for countersurveillance, and many other applications. The most important issue in these radars is to satisfy the low false alarm and correct detection. This work investigates the performances of the single tone harmonic radar and two-tone intermodulation radar in terms of the false alarm and correct detection rate by performing some experiments.
