Intelli-WAVE Microwave Protection System
Intelli-WAVE:Microwave Protection System • Volumetric, line-of-sight perimeter intrusion detection system - X-band radar • Dielectric Resonant Oscillator for greater frequency stability over temperature range • Adjacent channel rejection - six field selectable channels with greater than 60 dB. rejection between • Preamplifier for higher fade margins & greater applications • Field adjustable - phase lock loop (PLL) signal processing with user adjusted sensitivity for optimum detection
Intelli-WAVE Microwave Protection System • Range from 3 to 183 m • Tamperproof - completely enclosed in rugged all-metal housing with integral rain shield • Audible side-tone - output proportional to radar target velocity & cross section for alarm assessment and troubleshooting • Easy installation - transmitter and receiver install on posts • Low current operation - less than 75 mA/12 VDC • Built-in lightning suppression on all inputs and outputs
Intelli-WAVE: Microwave Protection System • Polarization diversity: rotatable antenna arrays • Remote self test input • Self-supervising transmitter option (power only) • Built-in LED bar graph for alignment • Optional multiplex communications • Rear access to electronics without disturbing the alignment • FCC certified • Trouble free reliable operation - 15 year MTBF Receiver Modular Components
Where to use Microwave Sensors • Open outdoor storage areas • Sallyports in Correctional applications • High security areas with dual fences • Trucking companies • Gas and Oil storage sites • Nuclear power generating sites • Nuclear fuel storage sites • Power utility substations • Roof top applications for traps
Microwave Protection System: Do and Don’t List • Do use in clear areas where you have clean line of sight - Detection zone should be long and flat • Don’t use in areas where line of sight will be blocked, such as; parking areas, near fixed objects in beam (out buildings, guard shacks), power or light poles in direct center of beam • Do use in areas where ground is smooth • Don’t use over drainage ditches, ungraded areas where there is more than 6 inches change in terrain over the length of the zone
Microwave Protection System: Do and Don’t List • Do use in area which is free of extraneous motion • Don’t use in area with trees or shrubs in or near detection zone. Vegetation within detection zone will cause nuisance alarms. Don’t use near large areas of water, such as: ponds, streams, drainage ditches, property run off areas. • Do use in area that is fenced • Don’t use in unfenced areas because of problems with animal-caused nuisance alarms
Microwave Protection System: Do and Don’t List • Do mount Microwave link zone at least 15 feet in from the fence line • Don’t mount the Microwave link too close to the fence as it will make it easy to jump over the beam and fence movement can cause alarms • Do keep links out of traffic areas and provide protective devices to prevent damage • Don’t mount links near fence gates that can swing into the heads
Microwave Protection System: Ground Cover • Crushed rock is best ground surface to deploy microwave links over • Crushed rock allows proper drainage of rainwater and prevents puddling • If in snow area, pavement is most suitable surface. Pavement allows snow to be removed easily. Snow build-up can cause changes in microwave pattern and nuisance alarms • Well-mown grass (3 inches or less), asphalt, concrete, hard packed soil, are good for medium and low security sites.
Microwave Zones: Type of Security • High Security Zone • Detection of intruder stomach-crawling parallel to and through the beam • Medium Security Zone • Detection of intruder crawling on hands and knees through the beam. • Low Security Zone • Beam-break alarm only • Detection of a walking intruder, vehicles, etc.
Microwave Protection System: High Security Zones • Transmitter/Receiver separation distance no greater than 328 feet (100 meters) • Terrain must be level to grade, ±3 inches (7.6cm) • Terrain finished with crushed rock (1 inch max.) to a depth of 4 inches or paved zone completely void of vegetation • Transmitter/Receiver units mounted 24 inches beam centerline (center of antenna) to ground
Microwave Protection System: Site Design • Start by making detailed sight drawing • Show all dimensions, including terrain variations, drainage ditches, types of pavement, etc. • Zone placement must provide clear line-of-sight between transmitter and receiver • Zone length will depend on degree of security required. • High security zones may not be over 100 m • Medium Security zones may not be over 150 m • Low security zones may be up to 183 m • Trees, buildings in area may require shorter zones
Microwave Protection System: Site Design • Offsets • Microwave energy starts as a very narrow beam (6 inches wide) • Area immediately below and in front of transmitter and receiver are not protected • To compensate for this each zone must be installed to provide protection to its adjacent zone • Following charts depict proper offset placement based on a mounting height of 76 cm (30 in.) above ground (High Security Site)
