Latest Patents

Mangalore Sachidananda holds a patent for a method titled "Signal processing and systematic phase coding for mitigation of range." This invention proposes a novel technique for resolving range ambiguities and separating overlaid signals in Doppler weather radar systems. The method involves a special deterministic code for the phases of transmitted pulses, along with associated decoding and processing of return signals. During the decoding process, when the signal from one range interval is made coherent, the signal from another range interval exhibits a multiple split spectrum. These multiple spectra share the same shape but are offset from each other. The patent outlines processing steps to separate the overlaid signals and a procedure to estimate the spectral moments. A crucial aspect of this procedure is the magnitude domain deconvolution, which is also applied to a staggered PRT transmission scheme. This application enables the estimation of spectral parameters with a significantly lower standard error than known methods. Furthermore, the combination of magnitude domain deconvolution with special spectral processing effectively addresses the problem of ground clutter filtering in staggered PRT sample sequences.
