Towed Arrays

Thin-Line Digital Array

The M508 Hydrus Towed Array is a thin line digital array. The array streams digitized acoustic and non-acoustic sensor data. Hydrus is a low noise, low drag, low power and lightweight array making it ideal for towing from an unmanned vehicle. The Hydrus array can also be customized with greater than 64 channels. The array and tow cable are neutrally buoyant to support low speed tow. Hydrus includes acceleration cancelling hydrophones to minimize mechanical noise. The array is user configurable to less than 2.5 kHz sampling rate, and high/low acoustic channel gain to tailor performance to various applications. Non-acoustic sensors include depth, temperature, roll, pitch, and yaw.

Applications vary from marine surveillance, marine monitoring, anthropogenic noise monitoring, and detection applications.
