Non linear Junction Detector DT-824S

Technical Principles:

The non-linear junction detector (NLJD) is also called harmonic radar. It emits a fundamental wave signal, receives the 2nd, 3rd or even higher harmonic/combined wave echo signals re-radiated from the target, and detects them. It is a Radar system for target judgment, identification and detection. Compared with general fundamental wave radars that only receive fundamental wave signals, harmonic radars can not only obtain fundamental wave channel information from the target, but also obtain 2nd, 3rd and higher information. Besides, Harmonic radar has better clutter suppression than ordinary radar and has stronger filtering capability.

Natural objects generally do not have the ability to re-radiate harmonics, such as mountains, oceans, land, etc., and purely man-made objects such as metal blocks will not produce harmonic radiation. Only the place where two metals combine to produce oxides (MOM) will produce harmonic radiation. Wave radiation, the most representative is the metal oxide and semiconductor PN junction.

In view of this characteristic, NLJD can be used to detect various electronic equipment, explosive electronic control devices, eavesdroppers, recording equipment, etc.

Application scenarios:

Non linear junction detector can be widely used in government, public security, prison, justice, army, education examination, business security and personal privacy protection, etc.

Business Safety: Detecting unauthorized electronic devices, such as eavesdroppers, mobile phones and devices with SIM cards, hidden in company board rooms or secret offices;

Public Safety: Detecting electronic devices hidden or prohibited from use in safe areas, such as detonating devices, remote controllers, etc.

Personal Privacy Protection: Hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.
