The Integrated Acoustics Console is a multi-function package of acoustic sensors capable of operating as a standalone system or as part of an integrated sonar suite. Designed for both surface warships and submarines, the system consists of phased array transducer(s), a broadband, software defined acoustic transceiver, control console displays and remote displays.
To improve signal-to-noise ratios, the watertight transceiver can be mounted in proximity to the transducers and networked to the control displays (and existing shipboard tactical systems) via serial interface or Ethernet.
The software defined transceiver can be dynamically tuned from 1 kHz to 2 MHz. The transceiver utilizes advanced modulation and digital signal processing techniques to significantly improve range resolution and target discrimination when compared to conventional fixed-frequency devices. The software defined architecture enables signal processing to be performed in the transceiver’s FPGAs that can be reprogrammed “on-the-fly” for desired function, frequency, bandwidth and pulse length. In addition to standard CW modulation, the Integrated Acoustics Console can utilize FM CHIRP.
The system utilizes CommandView software to process and display acoustic sensor data in real time. The software uses extensive pixelshading technology that allows CommandView to produce superb graphics. Other features include a customizable split-screen feature that enables side-by-side displays of any sensor function. This lets users create a display for any configuration they require, offering extensive overlay capabilities. Other functions provide more limited levels of customization, retaining the look and feel of the traditional analog instruments they reflect.
