Nonlinear junction detection technology, by using the principle that a nonlinear junction target can generate new frequency components under the irradiation of electromagnetic waves, detects and judges whether the target object contains electronic devices or metals. This technology may be popularized in and applied to the fields of wiretap-electronic-equipment detection, anti-terrorism and riot inspection, and anti-stealth harmonic radar. Firstly, the advantages in using non-linear junction detection technology to detect wiretap electronic devices are described, then, the nonlinear junction volt-ampere characteristics represented by the PN junction analyzed, and the Taylor-formula-developed current expression after illumination at a specific frequency derived, and then the principle of harmonic radiation analyzed, the design of nonlinear junction principle prototype carried out. And finally, the problem to be solved by the technology is discussed, and its application prospect forecasted.
