Key Competitive Advantages
There is no analogue in the world.
The user can analyze not only the amplitude, but also the spectra of the 2nd and 3rd harmonic signals re-emitted by a nonlinear object according to the scanning frequency, which increases the informational content of the nonlinear properties of the object. In particular, it significantly simplifies decision making about corrosive and artificial semiconductors.
There is a built-in module that measures the strength of the reflected sounding signal from the research object, giving the possibility to estimate the extension of the reflective surface of the object.
The use of 3 interchangeable transmit/receive units provides significant advantages in all three frequency ranges, significantly reducing the chance of missing out on research operations:
- 800 MHz – relatively low signal attenuation in all weather conditions in dense environments (such as brick, concrete).
- 2400 MHz - possibility to detect SIM multiples and small (about 1 cm²) semiconductor devices,
- 3600 MHz – providing selection that simplifies research work in buildings with legitimate electronic equipment.
Replacing the transmitter/receiver units and the extension bar will not take more than a few minutes.

Non-Linear Detectors Working Principle
The nonlinear junction locator, known as a semiconductor units detector or nonlinear transfer detector, is designed to detect devices containing semiconductor materials (diodes, transistors, circuits). Non-linear joint locators are used to detect remote control units of developed explosive devices, as well as detect electronic eavesdropping devices.
The working principle of the non-linear locator represents the high-frequency signal radiation of the object under investigation and the visual and auditory analysis of the second and third harmonic signal levels from the object. The non-linear joint locator is a mandatory device for any technical security service and its substitute law enforcement agency.
The operation of Lornet detectors depends on the properties of the local conductive components to create a reaction at the 2nd and 3rd harmonics when emitted by an RF sounding signal. In turn, semiconductor components of natural origin (eg, oxide membrane) will have a higher order of third harmonic reaction, while semiconductor components of artificial origin will have a higher order of second harmonic reaction. detectors; They analyze the 2nd and 3rd harmonic reactions of emitted objects that allow fast and reliable identification of electronic devices and natural oxide semiconductors.
The detectors automatically find the best noise-free and distortion-free receiver frequency, ensuring flawless operation even in complex electromagnetic environments. The frequency tuning algorithm built into the Lornet detectors automatically selects the RF sounding signal frequency so that the digital processing of the demodulated signal has maximum sensitivity while keeping the noise level in the 2nd harmonic receiver channel to a minimum.
