Growth Drivers

  • Augmentation in Maritime Border Security – There’s an increase in the demand for towed array sonar systems because of the growing developments associated with the protection operations and advancements in anti-submarine technologies amongst others. Additionally, the major players are making significant investments in research and development projects focused on underwater monitoring.
  • Increasing Usage of Towed Array Sonar in Fishing and Oil & Gas Industry- The demand for towed arrays for seismic streamers for the offshore oil industry and fish detection by acoustic methods. Moreover, the amount of fish delivered around the world is also propelling the market growth at a higher rate. With over 35% of the world's fish and seafood production in 2020, the People's Republic of China will be the leading producer of aquatic products. A historical growth, owing to high demand for supply resulting in the enlargement of fishing and aquaculture with significant production, consumption, and trade, took place in 2018.
  • Increasing Investment in Research and Development – But at night, when traditional optical cameras can't record the image, humans find it difficult to monitor them. However, when conventional optical cameras cannot capture images at night, it is harder for the human eye to watch. Market growth is expected to be stimulated by the growing development of a technologically advanced underwater optical camera, capable of capturing sonar images. For example, a detailed image of the aquatic environment, regardless of water visibility, has been developed by the SCAN650 sector scanning sonar.

Challenges

  • Negative Impact of Sonar Technology on Marine Ecosystem – There are many factors affecting the marine life such as seismic noise or the usage of sonar technology for underwater warfare and energy exploration. These factors result in injury and death of the marine animals. This factor is expected to become a barrier for the towed array sonar market.
  • Highly Costed
  • Maintenance Complexities

Towed Array Sonar Market Segmentation:

Type Segment Analysis

Passive towed array sonar is expected to garner the highest revenue in the forecast period. Also, the market is growing at the highest CAGR of 5% throughout the forecast period. The demand for passive towed arrays is increasing owing to their salient features such as prohibiting the emission of their own signal. Also, with the existence of a ping system, the enemies can easily detect the vessels.

Component Segment Analysis

The hydrophone segment in the towed array sonar market is estimated to hold a share of 80% by 2035. This sonar device consists of a system of hydrophones, which are tugged far beyond the submarine through cables. Such hydrophones are often kilometers from each other, thus enhancing the signal-to-noise ratio significantly. In order to detect and track faint sounds, e.g. lower noise emitting submarine threats or seismic signals, the towing array sonar shall be able to operate effectively. The salient features provided by the towed array sonar are driving the growth of the market in the military and defense industries.
