INTREPID™ Model 336 Long Range Digital Microwave Link

INTREPID™ Model 336 is a standalone volumetric perimeter detection sensor for fencelines, open areas, gates, entryways, walls and rooftop applications. Based on Southwest Microwave’s field-proven microwave detection technology, advanced embedded Digital Signal Processing (DSP) discriminates between intrusion attempts and environmental disturbances, mitigating risk of site compromise while preventing nuisance alarms.

Designed for maximum protection against sabotage, Model 336 is a high-security solution for security-sensitive sites such as nuclear plants, correctional facilities or government / military installations. Heavy-duty components and packaging, integrated radome tamper switches and optional steel enclosures for external wiring and connections prevent physical abuse. Integrated EMI/RFI shielding protects sensor electronics against external electromagnetic or radio frequency interference. The unit’s standalone configuration and on-board relay alarm outputs for monitoring eliminate the risk of hacking or other digital compromise faced by networked devices.

Model 336 operates at K-band frequency, achieving superior performance to X-band sensors. Because K-band is 2.5 times higher than X-band, the multipath signal generated by an intruder is more focused, and detection of stealthy intruders is correspondingly better. K-band frequency also limits susceptibility to outside interference from air/seaport radar or other microwave systems.

Antenna beam width is approximately 3.5 degrees in the horizontal and vertical planes. A true parabolic antenna assures long range operation, superior beam control and predictable Fresnel zones. Advanced receiver design increases detection probability by alarming on partial or complete beam interruption, increase / decrease in signal level or jamming by other transmitters.

Model 336 features 6 crystal-controlled, field-selectable modulation channels with narrow band filtering, preventing interference between sensors. Units can be dual, triple or quad-stacked for ultra-high security applications
