1. Purpose: Detects electronic components and semiconductor junctions hidden in devices, walls, vehicles, or luggage, commonly used to find hidden electronics, bugs, or improvised devices.

  2. Non-Linear Detection: NLJDs emit radio-frequency signals and detect harmonics generated by semiconductor junctions (diodes, transistors, ICs), distinguishing them from ordinary metal objects.

  3. Intelligent Features: Modern NLJDs include automated scanning, digital signal processing, sensitivity adjustment, false alarm reduction, and data logging for analysis and reporting.

  4. Applications: Widely used by military, law enforcement, counter-intelligence, security agencies, and anti-espionage teams for surveillance detection and security sweeps.

  5. Portability & Deployment: Available in handheld, backpack, or vehicle-mounted configurations for indoor, outdoor, or vehicular sweeps, providing flexible operational use.

  6. Integration & Output: Many intelligent NLJDs can interface with mapping software, GPS, or cameras to mark detected device locations, and offer audio/visual alarms for detected junctions.
