Long Range Microwave Intrusion Detection Links - Model 316 Detection up to
244m (800ft) CE Certified. K Band
- Intrusion detection, using a modulated amplitude sensitive system
(not Doppler), takes place within the invisible pattern of microwave energy
existing between transmitter and receiver. Changes in signal amplitude at
the receiver are directly related to the object’s size and density, allowing
the sensor to discriminate between objects.
Model 316 will alarm on
average sized humans walking, running or crawling on hands and knees through
the pattern.
Field adjustments can provide alarm on larger or smaller
targets, depending on the specific application. The surface mounted
electronics and antenna of Model 316 are mounted on a rugged metal
base-plate and covered by a molded ABS radome. Swivel mount permits precise
setup and provides firm lock against movement. |

Our Outdoor Microwave Models operate in the K-band frequency
band, and achieves performance not possible with ordinary X-band microwave
links (which operate between 9.4 and 10.5 GHz). Antenna beam-width is
approximately 3.5 degrees in both the horizontal and vertical planes. This
means that our Microwave Models will operate at long ranges and within very
narrow corridors. The 316 fully complies with the EC emission requirements
of EN300 440.
Each
Model Transmitter and Receiver is packaged in weatherproof housings, which
are only 269mm (11.6 in) in diameter and weigh only 2.0kg (4.4 lbs).
Comparable X-band systems require housings which are over twice as large.
This small size provides optimum resistance to wind-loading and obvious
advantages for installation.
Because its K-band microwave frequency is 2.5 times higher than the X-band,
the multipath signal generated by an intruder is 2.5 times higher and
detection of slow-moving intruders is correspondingly better. With superb
beam control and higher multipath frequency, our Microwave Models provides
unmatched detection performance. |

The
narrow band receiver design increases detection probability by alarming on
partial or complete beam interruption, increase or decrease in signal level
or jamming by other transmitters. Its Automatic Gain Control (AGC) circuit
permits the receiver to compensate for varying site conditions or changes in
the weather.
Operating at K-Band, which is much less crowded than X-band, Model 316 is
inherently less susceptible to outside interference from airport landing
systems, aircraft radar, and other microwave intrusion systems. Six
field-selectable crystal controlled modulation channels with narrow band
filtering allow several Models to be used together without mutual
interference. Microwave Models can also be stacked with an X-band link, such
as Southwest Microwave Model 300B, with no danger of mutual interference.
Such an arrangement provides the ultimate in detection performance and
extremely high resistance to electronic jamming. Our other Microwave
Intrusion Detection Models operate at different specification providing the
following ranges: Model 380 61m (2O0ft), Model 385 122m (400ft). |
