Recent Patents in Signal Processing (November 2011) - Radar Signal Processing

For our November 2011 edition, we focus on patents in the area of Radar Signal Processing. The selection below includes patents issued in the recent past, ranging from deblurring, resolution enhancement, and clutter filtering of radar images, applications to vehicular radar, and fundamentally new architectures and acquisition methods based on ramp signals, OFDM signals. If you have an interesting patent to share when we feature Radar Signal Processing-related patents the next time, or if you are especially interested in a signal processing research field that you would want to be highlighted in this section, please send email to Shantanu Rane (rane AT merl DOT com).
