ISS360HD Sonar Imaging
Broadband CHIRP Imaging Sonar
Description
The Impact Subsea ISS360HD is a high resolution imaging sonar in a titanium housing. It combines a broadband composite transducer with a digital acoustic engine, and uses CHIRP (Compressed High Intensity Radar Pulse) acoustic signalling to increase range resolution. The ISS360HD has no slip rings.
The Impact Subsea ISS360HD operates at 750 kHz centre frequency with 600–900 kHz bandwidth and covers a range of 0.45–100 m with 2.5 mm minimum resolution. The beam angle is 30° vertical and 1° horizontal at 700 kHz. Signalling is selectable between CHIRP and CW, step size is selectable between 0.225°, 0.45°, 0.9°, 1.8°, 3.6° and 7.2°, and the sonar scans 360° continuously or in sector scan.
Integrated pitch and roll is available (optional), with pitch ±90°, roll ±180°, 0.2° accuracy and 0.1° resolution, so sonar imaging, pitch and roll can be provided from a single device. The ISS360HD is rated to 6000 m, operates at −10 to 40 °C and weighs 0.76 kg in air and 0.3 kg in fresh water. It communicates over RS232, RS485 and Ethernet at 9600–115,200 baud, runs on 12–65 V DC and uses a Subconn MCBH8M-SS connector (other options available).
Applications listed for the Impact Subsea ISS360HD include ROV and AUV navigation, target identification, diver navigation, port surveillance, motion reference and search and recovery.
