Naval meteorology

In naval meteorology, accurate atmospheric information is critical for navigational purposes and as input into the onboard weapon and self-defence systems. In addition, knowledge of wind conditions is essential for safe helicopter take-off and landing onboard.

Vaisala offers a suite of weather measurement systems that can improve onboard systems performance. We have decades of experience in deploying naval meteorological systems, support and training around the world.

Electro-optical sensor performance

Meteorological phenomena affect the performance of optical- and IR detection, and high frequency radar and communications systems. This may result in reduced performance in detection of high speed, non-cooperative targets, and onboard self defense and weapon systems. Some important meteorological phenomena are:

• sub- or super refraction
• ducting
• strong attenuation
• termperature profile close to the sea surface
• visibility

Maritime patrol aircraft with airborne radar systems can predict surveillance coverage using dropsonde observations of refractive conditions, and perform accurate dropping of sonar buoys from high altitudes.
