DSIT Solutions publicly unveiled its new multimission sonar system designed for operation onboard underwater vehicles at the Undersea Defence Technology (UDT) 2024 conference and exhibition, held in London from 9 to 11 April.

The system, named DogFish, was developed in response to the proliferation of threats in the underwater environment from manned and unmanned vessels. It has the capability to autonomously detect, track, and classify submarines, mini-submarines, semi-submersible vehicles, moored mines, and autonomous and unmanned underwater vehicles (AUVs/UUVs).

DSIT describes the system as small, lightweight, and featuring a very low signature that makes it particularly suitable for anti-submarine warfare (ASW) and homeland security missions. Its main components comprise a 360° transmitter array, two receiver arrays, an electronic unit, and a shore data analysis system.

DogFish can be integrated onboard any type of underwater vehicle and can operate in active or passive modes, or in both simultaneously at medium to high frequency in both littoral and deep water. It utilises artificial intelligence, machine learning, automation algorithms, and latest-generation signal processing and acoustic techniques to provide a high level of situational awareness.

Speaking to Janes at UDT 2024, Hanan Marom, DSIT's vice-president for business development and marketing, said that DogFish leverages technology developed for the company's proven and fielded AquaShield diver detection sonar system, which has been in service with the Israeli Navy for more than 15 years and features a high rate of accuracy for threat detection of around 99.9% – which is the equivalent of less than one false alarm every 24 h.
