The CAPTAS-4 is a towed array sonar developed by Thales Underwater Systems to equip first-rank surface combatants.Manufactured in Brest, France, it represents the high-end and most powerful system of the company's CAPTAS (Combined Active and Passive Towed Array Sonar) line of products [1] and equips several first-rank warships of the French Navy as well as those of various export customers.
Escape from Tarkov is a multiplayer tactical first-person shooter video game in development by Battlestate Games for Microsoft Windows.The game is set in the fictional Norvinsk region in northwestern Russia, where a war is taking place between two private military companies (United Security "USEC" and the Battle Encounter Assault Regiment "BEAR").
Some species of hawkmoths (Sphingidae) produce ultrasound capable of sonar jamming. [25] Sonar jamming capability has evolved independently in at least six subfamilies. [26] Because sonar jamming seems to require high duty cycle ultrasound, it is believed to be a derived form of the simpler ultrasound used for aposematism and mimicry. [27]
Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water . It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight , along with knowledge of the speed of sound in water, allows determining the distance ...
JH Audio JH16 Pro IEMs, with a custom-molded hard acrylic shell Elize Ryd wearing in-ear monitors during a concert in 2018. In-ear monitors, or simply IEMs or in-ears, are devices used by musicians, audio engineers and audiophiles to listen to music or to hear a personal mix of vocals and stage instrumentation for live performance or recording studio mixing.
Each system, from shore facility to the transducer array was a sonar set with the signal processing beginning as the array's signals were amplified, processed into beams by time delay and each beam processed by an electromechanical spectrum analyzer with the display being a sweep of the frequency spectrum's intensity burned across electrostatic ...
Sodar systems are in fact nothing more than sonar systems used in the air rather than in water. More specifically, since they operate using the Doppler effect with a multi-beam configuration to determine wind speed, they are the exact in-air equivalent to a subclass of sonar systems known as acoustic Doppler current profilers (ADCP). Other ...
Multibeam sonar is used to map the ocean floor. A multibeam echosounder (MBES) is a type of sonar that is used to map the seabed. It emits acoustic waves in a fan shape beneath its transceiver. The time it takes for the sound waves to reflect off the seabed and return to the receiver is used to calculate the water depth.
