This website has been developed to make a large number of high quality and well documented sea clutter data sets available to the radar research community. The data are measured with the McMaster IPIX Radar, a fully coherent X-band radar, with advanced features such as dual transmit/receive polarization, frequency agility, and stare/surveillance mode. It is extremely versatile, as each feature is highly adjustable through software in the control computer.

In the summer of 2001, while revisiting the nonlinear dynamics of sea clutter at the Adaptive Systems Lab, we concluded that at timescales larger than several seconds, gravity and swell waves cause sea clutter to be modulated in amplitude and frequency, and in width and shape of its short-time Fourier transform (Doppler spectrum). These four modulation processes are highly dependent on sea state and radar orientation with respect to wave direction, and are subject to further study. We hope that this website will encourage others to contribute to this exciting field.




What does I.P.I.X. stand for?
The radar was originally developed for iceberg detection, and IPIX was a shorthand for 'Ice Multiparameter Imaging X-Band Radar'. After major upgrades between 1993 and 1998, the high resolution data measured by the radar became a benchmark for testing intelligent detection algorithms, and the meaning of the acronym changed accordingly into 'Intelligent PIXel Processing Radar'.
How can I obtain more datasets, besides the ones made available on this website?
Write a letter to Simon Haykin, indicating the proposed research and motivating us to copy the CD-ROMs and send them to you.
