July 2019 – TD 304 OPERATING MANUAL – Doppler Current Profiler Sensor

Page 47

The two methods have their own advantages:

Broadband

gives a lower single ping standard deviation which requires fewer ping (lower energy usage) to get

a good measurement result. The disadvantage in

Broadband

is ambiguity. If the sensor is fixed, for example

when deployed in a bottom frame, the ambiguity is not a problem (ambiguity lock disabled). If it is moving and

the user knows that the current speeds are always below 1 m/s, enable the ambiguity lock.

If the sensor is moving (as under a buoy for example) and the current speeds are higher than 1m/s, it is

recommended to use

Narrowband

. Though

Narrowband

is more power consuming than

Broadband

, the

reached measuring range is slightly longer than in

Broadband

mode.

Enable Ambiguity Lock

is only used with

Broadband

. In

Broadband

the output of the correlation process is a phase

value. When the Doppler shift is zero then the phase is also zero. When the Doppler shifts increase, so will the phase. A

Doppler shifts of approximately 1.25 m/s along the beam corresponds to a phase equal to 360 (360 = 0) which is exactly

the same as for zero Doppler shifts. For this reason the cross correlation process is not able to distinguish a Doppler

shift of 1.5 from a Doppler shift of zero. In fact any Doppler shift outside the 1.25m/s range will be wrongly detected to

be within the range 0 – 1.25 m/s. This is called ambiguity and could hamper the correct operation of the instrument if not

corrected for. If ambiguity lock is enabled the result will stay in the first loop also between 0 and 1.25 m/s so if you know

the current will be below 1.25 m/s you can use

Ambiguity Lock

and avoid any error caused by ambiguity,

In case the ambiguity lock is not selected, several stages of ambiguity solving methods are automatically implemented

in the DCPS in order to achieve a non-ambiguous solution.

Ping Number

is the number of ping transmitted during one recording interval. One ping is a transmitted pulse from all

transducers. These four pulses are sent out simultaneously in four directions.

Enable Burst Mode

. The sensor can run in burst mode or spread mode. When burst mode is enabled the sensor

performs all ping measurements at the beginning or end of the recording interval, dependent on the Burst Period

Placement setting. This can be set to either

Start Of Interval

End Of Interval

. If it is disabled the ping measurements

are evenly spread out during the recording interval. The instrument activates sleep mode between each measurement,

which reduces the power consumption. Power consumption in spread and burst mode is about the same.
