Kaon’s founding expertise is in sonar technology. We pride ourselves in the high level of design/development and support we provide to enable the next generation open architecture sonar, specifically, inboard processing systems for Low Frequency Active (LFA) transmit and receive. We continue to innovate in this technology area providing such systems as advanced spatial awareness displays for Z-Scan displays.

Kaon has worked with a number of different organisations both in the UK and abroad, these include UK MoD, NATO, Dstl, FWG of Germany, QinetiQ and Thales Underwater Systems, on multi-nation active trials programmes. Our employees have been a part of many of the UK LFA trials programmes over the last 10 years and have provided support on mono-static, and multi-static trials.

Our knowledge of sonar active processing systems and how LFA systems are used in the real world complements our domain experience for the environmental protection of marine mammals.

Our breadth of experience covers many areas within this field and includes but is not limited too:

LFA Receiver

A multi-processor receiver capable of interfacing to a number of different towed arrays providing beamforming, active processing for continuous waveform (CW) and matched filtered (MF) returns and open access to all output data streams. The processing system is capable of interfacing to single/multi octave single line and triplet arrays. The MF sub-system contains many features for processing wideband signals and various Doppler schemes.





Multi-static Contact Sharing

A system developed as part of a multi-national active trials programme to automatically detect potential targets, and then share contact data from the active sonar returns across a flotilla of platforms operating in formation. This was the first step towards network enabled multi-static sonar capability. This type of technology is important as the best returns from a target may be received mono-statically (by the transmitting vessel) in some cases and bi-statically (by another receive only vessel) in other cases, dependant on the geometry of the target and sensors. Fusing the results gives the best results in all scenarios.

Echo Repeater

A totally autonomous active detection and transmit system which functions without the need for an operator and is suitable for onboard submarine use. The echo repeater can be programmed to automatically detect any input active transmission type. Once detected the system repeats the transmission waveform with a configurable target strength.

WBA Transmit System

A transmit control system used on a number of multi-national active sonar research sea trials. The system is capable of controlling up to eight S11-48 Class D Instrument Inc. Power Amplifiers for multi-octave transducers. Significant flexibility in the waveform generation and control schemes allow any frequency cross-over technique to be adopted. The system is controlled via XML run plans.
