Orion provides the capability to detect hidden electronic devices, regardless of whether the device is radiating, hard wired, or even turned on at all! Orion is the latest advancement in Non-linear Junction Detection and evaluation for Countersurveillance.

Back in the early 70's a method was developed to detect eavesdropping devices though the analysis of harmonic emissions caused by an illuminating signal when it is reflected off of a target.

Semiconductors contain multiple layers of silicon, a P-Type and an N-Type, the point where they meet is called a Non Linear Junction. This junction also appears in nature when dissimilar metals come in contact with one another (such as that used in the old crystal radio set). Also, the rust on a screw, the springs in a car, or the support structure in any piece of furniture may also contain non-linear junctions (resulting from corrosion).

A Non-Linear Junction Detector finds potential eavesdropping devices by flooding a suspect area or target with a spectrally pure microwave RF signal (usually around 888 or 915 MHz). Various frequencies are then monitored for a reflected harmonic signal.

The instrument typically has an antenna and a control unit. The antenna is mounted on an extendable pole, and really nothing more than a microwave waveguide which both emit and collects the signals (with a duplexer). The control unit is usually a multiple channel, highly sensitive radio receiver tuned to specific second, and third harmonic frequencies. While it is possible to measure the 4th, 5th, 6th, and other harmonics those above the third are only of limited TSCM value.

NJE-4000 Advantages:

• Minimum Set-up Time, no cables or bulky transceiver units to carry.
• Lightweight, balanced ergonomic design for ease of use.
• High Transmit power for rapidly searching a large area. Circularly Polarized Antenna reduces search time and improves reliability.
• Dual Harmonic with Discrimination Algorithms Minimizes False Alarms.
• Standard type camcorder battery with long use time and quick charge function.
• Wireless Headphones and Graphic Display for simultaneous Audio & Visual Information.

NJE-4000 Advancements:

• 2nd and 3rd harmonic operation includes advanced algorithms for minimizing false alarms as well as listening capability for each harmonic.
• Dynamic power control for locating threats; automatic or manual control (10 mwatt to 1 watt).
• Synthesized transceiver provides frequency stability and agility to automatically search for clean operating frequencies (Frequency range 902-928 MHz for U. S. Models and 850 MHz to 1,000 MHz for Export Models).
• Circular, polarized antenna removes risk of missing a threat due to incorrect antenna polarization.
