Hydrophone
INTRODUCTION
A Hydrophone is a device which will listen to, or pick up, the acoustic energy underwater. A hydrophone converts acoustic energy into electrical energy and is used in passive underwater systems to listen only. Hydrophones are usually used below their resonance frequency over a much wider frequency band where they provide uniform output levels.
Underwater echo detection systems were developed for the purpose of underwater navigation by submarines in World war I and in particular after the Titanic sank..............etc

A hydrophone is a sound-to-electricity transducer for use in water or other liquids, analogous to a microphone for air. Note that a hydrophone can sometimes also serve as a projector (emitter), but not all hydrophones have this capability, and may be destroyed if used in such a manner.The first device to be called a 'hydrophone' was developed when the technology matured, and used ultrasonic waves, which would provide for higher overall acoustic output, as well as increasing detection. The ultrasonic waves were produced by a mosaic of thin quart..............etc

Abstract
One form of cooperative behavior for a group
of AUVs is to fly in formation while performing tasks.
A necessary component for formation-flying is that the
vehicles must sense their relative positions.
Assuming that each vehicle is capable of sensing its
inertial position using an acoustic long-baseline
ranging system, the relative vehicle position can be
determined by exchanging this data. The penalty for
this approach is that exchanging inertial position data
consumes communications bandwidth. Alternately,
relativ..............etc
