NL RADAR 1420 - Non-linear Junction Detector
Multi-frequency non-linear junction detector NL RADAR 1420 is designed for search for and detection of electronic devices both in active and switched offstate. Multi-frequency harmonic detector searches and analyzes the 2nd and 3d harmonics at each probing frequency. A detector that uses two and more probing signals simultaneously at different frequencies is hereinafter referred to as a multi-frequency mixing detector. It can analyze products called 2nd and 3d order distortions: F1-F2 ; F1+F2: and 2F1-F2; 2F2:-F1, respectively. NL-1420 is an example ofsuch a detector.
NL RADAR 1420 is classified as a multi-frequency harmonic detector. Probing frequencies are chosen within the range of 1400-2000 MHz. There are 4 probing frequencies with frequency space of 200 MHz. It increases the detection range greatly. Besides, a patented phase antenna array (PAA) for frequency range of 1400-2000 MHz and a patented PAA for receiving frequency of (2800-6000) MHZ also increases the detection range due to high gain ratio of PAA (about 13 dB). NL RADAR 1420 consequently analyzes re-emitting signals at four frequencies and chooses a maximum response automatically. A short probing pulse of 150 ns virtually eliminates the possibility of triggering radio electronic active devices, which makes it possible to effectively search for explosive devices with a radio switch. Climatic version of IP 67 expands operational-tactical characteristic of the device.
