Summary on Grant Application Form
From the early 1990's there has been much interest in the application of chaotic systems to communications. Many of these systems show poor tolerance to noise and distortion within the channel. While the properties of the chaotic waveform offer much potential, the practicality of getting the receiver to synchronise with the transmitter compromise performance. This is a consequence of not knowing the shape of the waveform being transmitted (only some of the parameters of the defining equations). This fundamental problem does not exit when the transmitter and receiver are collocated and can therefore share information. Such a configuration has limited use for communications, but is typical of the configuration used for radar and sonar. Despite this fact, there has been little published research on the application of chaotic systems to radar or sonar.Dr Williams has an international reputation for his research on the impact of the channel on chaotic communication systems, and consequently has been invited to present his work in relation to sonar and radar systems at the SIAM conference Application of Dynamical Systems . The key issue in radar/sonar systems is to be able to detect the presence of a returnng signal, and to accurately determine the round trip time for each signal. This is difficult when multiple returns exist due to multiple reflections within the channels.There have been very few conference sessions focussing on chaos with chaos and radar. It is expected that the main researchers in the field will be present, and so this presents an excellent opportunity to discuss collaboration between US and UK research teams (and possibly wider). It is therefore the intention to hold an additional workshop session to discuss ongoing and future research programmes, and subsequently the potential for collaboration between research groups. Fundong is therefore requested to support Dr Williams to attend the conference and organise an additional workshop for discussion on collaboration.After the workshop, the presentations and discussions will be written into a document that will be circulated widely within the US and UK research communites to generate further interest in collaboative research.
