Patent Number Title Of Patent Date Issued
8274423 Sensitivity enhancement system September 25, 2012
Sensitivity is a critical aspect of weather radar systems. Such systems not only detect atmospheric patterns but often need to precisely measure weak precipitation echoes. Embodiments of the invention use pulse compression techniques to increase the sensitivity of weather radar syste
8164512 Gaussian model adaptive processing in the time domain April 24, 2012
Embodiments of the present invention provide a Gaussian adaptive filter for ground clutter filtering and signal parameter estimation for weather radars in the time domain. In some embodiments, the filtering can be applied to dual polarization radar systems. In some embodiments, the c
8077074 Networked waveform system December 13, 2011
Certain embodiments provide a network waveform system that can include multiple radars disposed at different geographical positions within an environment. The multiple radars may be configured to transmit a network waveform. The network waveform may include multiple radar waveforms. Each
7898459 Adaptive specific differential phase in dual-polarization radar March 1, 2011
Systems and methods are provided for adaptively estimating the specific differential phase (K.sub.dp) from dual-polarization radar data in the complex domain. Some embodiments adapt for wrapped differential propagation phases by estimating the specific differential phase in the compl
7843378 Dynamic and adaptive radar tracking of storms (DARTS) November 30, 2010
Methods and systems for estimating atmospheric conditions are disclosed according to embodiments of the invention. In one embodiment, a method may include receiving reflective atmospheric data and solving a flow equation for motion coefficients using the reflective atmospheric data.
7652614 Ground clutter mitigation using a parametric time domain method January 26, 2010
Methods and systems are disclosed for investigating a region of interest with a radar. A radar signal is propagated to the region of interest. Sampled time-domain radar data scattered within the region of interest are collected. A likelihood function is calculated with the sampled ti
7583222 Method for using pulse compression in weather radar September 1, 2009
A system and method for processing data related to weather phenomena in a meteorological radar system. The method includes receiving an echo signal generated by transmitting a long pulse and employing a mismatched windowed filter on the echo signal such that the echo signal is compre
7518544 Retrieval of parameters in networked radar environments April 14, 2009
Radar beams are generated with radars disposed at different positions within an environment that attenuates at least a portion of one of the radar beams. A measured reflectivity of the environment is determined along a path of each of the radar beams. An intrinsic reflectivity is det
