Accurate atmospheric information is critical for the assessment of weapon system performance. It’s also important for improving passive countermeasures. The uneven distribution of water vapour close to the sea surface, together with temperature inversions, can lower the effectiveness of high frequency radar systems. This in turn can hamper the detection of high speed, non-cooperative targets.

Maritime patrol aircraft with airborne radar systems can predict surveillance coverage using dropsonde observations of refractive conditions. Vaisala offers a suite of weather measurement systems that can dramatically improve both weapon performance and shipboard defense. We have decades of experience in configuring naval meteorological systems, with over 100 systems in 20 countries. We are also able to offer worldwide support and training.
