Side-scan Sonar Survey is a type of Marine Survey which is used to efficiently and precisely map the larger areas of sea bed without any intrusion into the sea bed. Submerged ships, sea bed profile and other buried objects can be identified and mapped using this technique. Conical or fan shaped pulses are emitted from the sonar devise toed with the Boat or ship towards the sea bed across a wide angle through the water. The intensity of the reflections of these pulses from the sea floor is recorded in a series of slices to form an image of the sea bed. Pulses of different frequencies are used with different objectives as higher frequency beams provide better resolution but lesser range.
