美国FarSounder
美国FarSounder公司是一个专长于前视导航声纳的研究性企业。2001年起他们研发的3D前视声纳被推广应用到全球市场。在海洋导航领域被
广泛应用于防止触礁和搁浅、航道引航、障碍物避绕、科学研究、环境保护等方面。到目前为止，全球市场已经有130多套Farsounder前视声纳得到应用，每年为商用船舶、私人游艇、工程船只等避免了数以百万计美元的海难资金损失。为此，Farsounder公司赢得了多项发明专利和奖励。FarSounder的产品目前已经在中国包括海军东海舰队和中国国家海事局等单位和组织得到应用。

FarSounder is a developer and manufacturer of advanced 3D sonar systems for marine navigation, obstacle avoidance and security applications. The privately held company was incorporated in 2001 and has patented technology with four patents issued.

The first commercial product line was launched in 2004 with FarSounder's forward looking sonar technology delivering critical information by giving mariners the ability to "see-ahead," underwater, in true 3-D: with simultaneous range, bearing and depth information. The company has a worldwide distribution network with sales and installations globally. Markets sold to include passenger vessels, large yachts and commercial and government organizations. The company has won awards including the 2005 International ISTIA Award for best new technology for the Superyacht market.

Over the past several years, FarSounder has become known worldwide as the leader and innovator of marine sonar technologies. One facet of the company vision is to seek out opportunities across a broad range of market sectors. Unlike many marine electronics companies which limit their markets to one sector, the uniqueness of the FarSounder technology transcends the commercial, military and recreational markets.

The growing use and application of FarSounder's real-time 3D sonar technology may have a larger effect on the marine industry than even radar and GPS. This disruptive technology enables marine vessel operators to avoid costly and environmentally damaging collisions and groundings.

FarSounder has lead the way for such development through the use of new processing algorithms and innovative hardware configurations which overcome the significant limitations of traditional sonars that cannot provide range, bearing and depth to in-water obstacles for an entire 3D field-of-view, cannot operate well in shallow water environments, nor can they provide obstacle avoidance capability at navigationally significant ranges.
