Compact deepwater imaging sonar for ROV and AUV

forROVandAUVCompact deepwater imaging sonar

Impact SubsealaunchedISS360HDThis is a method used forROVThe new imaging sonar for remote-controlled vehicles can provide1°Acoustic angle resolution,2.5mmRange resolution and beyond100rice/ 328The distance measurement range in feet. The rated depth of sonar is 6，000 rice/19，685 Feet, very compact in appearance.

ISS360HDHas a very wide operational acoustic bandwidth capability;600to900kHz, throughCHIRPThe technology of compressing high-intensity radar pulses is fully utilized. Broadband widthCHIRPCan be provided when using full bandwidth2.5mmExcellent range resolution.

The combination of narrow sound beams and extremely short distance resolution can produce high-resolution images. This makesISS360HDBecoming a work levelROVThe ideal choice for operation, with excellent range capability and the ability to identify targets in zero visibility. The external dimensions of sonar are also the smallest observation levelROVProvided this ability.

belowISS360HDThe example image shows a harbor wall, a harbor floor with wheels, ropes, stones, etc. The figure also shows the mooring ropes of ships along the coastline (left) and on the water surface.

In addition to long-distance and high-resolution functions,ISS360HDAlso benefiting from inductively coupled transducers. This means that there are no slip rings inside the sonar, so there are no worn or regularly replaced components.

Sonar can be equipped with integrated pitch and roll sensors to provide accurate attitude readings. This is a very useful feature when deploying sonar using a tripod to ensure horizontal positioning and provide additional sensor readings for certain underwater vehicles.

In terms of connectivity,ISS360HDBenefiting from serial（RS232andRS485）Communicate with Ethernet. When using Ethernet communication, it has been found that the scanning speed of sonar is six times faster than that of serial sonar alone. When sonar is used for obstacle avoidance purposes in underwater vehicles, it provides significant benefits.

ISS360HDandImpact Subsea View V3Software can be used in conjunction withImpact SubseaAltimeter, depth sensor,AHRSSensors andFMDSeamless use of the system. For those who hope toISS360HDPeople who use sonar with autonomous underwater vehicles can receive a free software development kit to allow direct integration of sonar.
