My company for the British CMAX's sole agent in China, the United
Kingdom CMAX's CM2 digital dual-band sonar around the world who
owned a large number of quality customers, the Australian Navy has
ordered 15 sets of CM2, where they are more concerned with
performance rather than price; France Navy bought six sets of CMAX
products, while they use the original KLEIN and EDGETECH company's
products. CM2 winch has a unique advantage; Second, no other
company offers such a compact, waterproof USB interface transceiver
devices; dragged the fish with a balancer; hauling rope, rather
than the whole of stainless steel plating. MaxView collection is
the most easy to use package.
Particular emphasis was placed, CMAX sonar in Russia's possession
of more than half of market share.
Following is the president of the United Kingdom CMAX made for some
users, "while dual-band" work to clarify the fuzzy knowledge for
all to be understood from the principle of side-scan sonar should
be based on job requirements with the correct methods of work. Want
users to fully take into account in choosing the above factors.
Thanks! "At the same dual-band" is a product of history, is Huang calendar
of.
The early drag the fish due to the limitations of signal
transmission can be prevented acquisition system that delayed the
work of the fish should be best adapted to the frequency.
Therefore, the early drag the fish in two frequencies to send data.
Now, everyone can accept the fact, that is to say the same time,
there is no advantage of dual-band work. Each frequency has an
optimal range and resolution, it can not be very happy to mix.
Ranging in any setting, the better the higher the sampling rate
required to obtain a better image quality. But the largest sampling
rate (repetition rate) depends on whether you measure the maximum
distance measurement. Because the next wave of the launch of the
need to wait the longest before one can be issued after the echo to
come back. This means, for example: Set Range 50 meters (ie, scan
rate of 100 meters), this time sampling rate of the largest 15 / s;
This is the CM2 work 325KHZ maximum sampling rate to get the best
image.
If "the same time, dual-band" work, for example, set 100 meters
high-frequency sweep rate, while low-frequency sweep rate is set at
400 meters, which would seriously reduce the center sweep rate of
the image quality; this time a serious decline in high-frequency
image quality because the sampling rate must be reduced to 3.75
times / sec sampling rate to this value because of the
low-frequency echo must wait until the furthest back before
launching the next wave. Can not simultaneously transmitting
high-frequency sound waves.
Therefore, "the same time, dual-band" should not |
