Measurement and instrumentation :
Semantic TS studies instrumentation needs,
specifies, designs
and develops specific systems for measurement and processing, using
nowadays instrumentation techniques (networks, IEEE, RS232, numeric,
analogical ...). We have prepared and participated to several measurement
campaigns.
 | Measurement campaign : organization and realization
 |
Control and
calibration of measurement systems |
|
In the signal
processing domain : adjustment of measurements and
studying protocols, statistical processing of measured data, measurement
of noise directivity in 3D, measurements of vertical array directivity in
underwater acoustics,
time-frequency-temperature
measurements of quartz resonators (long and short time drift, temperature
stability …). |
|
In the study of propagation
medium :
investigation of underwater sound speed field using acoustic tomography ; investigation
of atmospheric layer using remote sensing; |
|
In the environmental
study : measure of current, density, sound speed, salinity
according to the underwater medium ; measure of pressure, temperature,
humidity, refractive index in atmospheric layers. |
|
Design of
methods,
control and calibration systems of array in underwater acoustics : in lake,
sea, pool … |
