Latest Patents

Among Shin's latest innovations, one noteworthy patent is titled "Method and apparatus for situationally adaptive processing." This patent addresses a signal processing method designed for echo-location systems, including radar, sonar, and laser radar. The method is adept at obtaining accurate estimates of target reflectivity sequences within a random (non-Gaussian) noise environment. This innovation tackles challenges posed by ambient noise, reverberation, and clutter by deriving the statistical characteristics of these random background environments. Furthermore, it constructs and maximizes the corresponding approximate likelihood function using iterative methods and yields maximum likelihood estimates through computationally efficient algorithms.

Another patent, "Method for automatic focusing of radar or sonar imaging systems," focuses on enhancing radar or sonar imaging systems, such as synthetic aperture radar (SAR) or synthetic aperture sonar (SAS). This innovative approach employs high-order measurements, like the quadruple product of the range-compressed signal. A recursive or non-recursive algorithm estimates the phase error from the quadruple product's phase, allowing the estimated error to be applied to the range-compressed SAR or SAS image data. This technique significantly improves the quality of focused image data.
