Operation of high-resolution, broadband, antisubmarine warfare sonars in littoral waters is challenging, since the presence of sea mounts, underwater ridges, and other topographic features causes increased false alarm rates. Two important contributor

In anti-submarine warfare, high resolution, broadband sonars are commonly used. This, however, might challenge the sonar operator in littoral environments as the sonar image often becomes cluttered due to false alarms. The origin of these false alarm

Use of high–resolution sonars in littoral environments generally result in high false alarm rates both due to false alarm rate inflation and non–Rayleigh reverberation. High false alarm rates may be handled by simply increasing the threshold used

During anti-submarine warfare operations, the use of high resolution broadband sonars often result in a false alarm cluttered sonar image. Correctly distinguishing between a sonar contact and a false alarm is a vital and complicated task for the sona

Operations involving active sonars in littoral environments are generally associated with reverberation limited sonar performance and large amounts of false alarms. The increase in false alarm rates is both due to the signal processing induced phenom

The use of high resolution, broadband sonars during anti-submarine warfare operations often result in a sonar image cluttered with false alarms. This may prove challenging for a sonar operator when it comes to correctly distinguishing sonar contacts

Anti-submarine warfare (ASW) operations in littoral waters can be challenging, especially in areas with topographical features and man-made objects that leads to increased false alarm rates. To maximize training benefit from operations in these areas

A well-known problem with modern anti-submarine warfare sonars with narrow beamwidths and wide frequency bandwidths, is the frequent occurence of false alarms, particularly in littoral environments. This increases the workload of sonar operators and

Modern anti-submarine warfare sonars are often designed with narrow beamwidths and wide frequency bandwidths in order to maximize spatial resolution and sonar performance. A known issue for high-resolution sonars in littoral environments, is the occu
