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). |
