Hi all,
I am currently trying to research into ASW technologies on ships. I am more interested in the submarine detection technologies, such as utilising the use of acoustics sonar or MAD which are usually used on aircrafts.
As far as sonar is concerned, i have done my research and found out that sonar can be categorised into 2 areas: passive and active. I am currently trying to establish the advantages and disadvantages of the use of the different active sonar applications, such as HMS, Towed Array Sonar (TAS), sonobuoy and active dipping sonar.
I am trying to do a comparison between HMS and TAS and have been trying to find out the advantages and disadvantages of HMS and TAS. However, all i could fins is that HMS is good for non-straight ship route but it can be affected by the acoustic noises from the ship itself. For TAS, it is only suitable for straight paths so that the array of hydrophone will not be affected.
For the comparison between sonobuoy and active dipping sonar, i cannot find much except that sonobuoy is expendable and is only valid within a localised area. Whereas, the active dipping sonar can have variable depths, depending on the mission requirement and sea conditions, however it can be affected by the acoustic noises from the ocean.
I have read a number of books and tried to find many sites to find more information the above 4 sensors, but to no avail. Therefore, i hope that i can tap on your expertise to help me with my comparison between HMS and TAS, and between sonobuoy and dipping sonar.
Thanks for your help!
