Abstract
The Canadian Navy has a continuing requirement to acoustically detect both surface vessels and submarines. The Defence Research and Development Canada (DRDC) through the DRDC Atlantic is embarking on the first phase of development of the next generation of operational sonars for the Canada Navy: the Towed Integrated Active Passive Sonar (TIAPS). The TIAPS Technology Demonstrator (TD) will demonstrate basic sonar capability and will serve as testbed for concept development. The TIAPS TD project (1cm) will integrate both active and passive sonars in a single system. By lowering the frequency from traditional hull mounted sonar frequencies and by giving the sonar a variable depth capability, longer range active detections can be achieved. Passive sonars have the advantage of being covert and allowing for the possibility of positively identifying a class of target by its acoustic signature. Not only will both active and passive capabilities be included in TIAPS, but also a high priority is placed on combining their capabilities. TIAPS will make use of the Sonar Information Management System to fuse sonar data with information from the ship’s Command & Control system, and will in turn provide information for the Command & Control function. In developing such a system, a number of sea trials are required. Q273 is the sixth in the series of R & D trials. Though Q273 is not a full sonar trial, acoustic transmissions are to be used to meet the trial objectives. In order to minimize
