Abstract: Aberration estimation uses cross correlation of receive-focused transmit element data. A set of sequentially fired broad transmit beams insonify an object from different steering angles. Each transmit beam emanates from an actual or a virtual transmit element. For every firing, a receive beamformer forms a transmit element image of the insonified region by focusing the received signals. An estimator estimates aberration by cross correlating or comparing the transmit element images. Where a virtual transmit element is used, the virtual transmit element images are back propagated to an actual transmit element position before aberration estimation. The estimations are used to form corrected transmit element images which are then summed pre-detection to form a high-resolution synthetic transmit aperture. Alternatively, the estimations are used to improve conventional focused-transmit imaging.

Abstract: Embodiments of the invention are directed toward attenuation correction of radar data. Atmospheric attenuation is a function of atmospheric water drop size and temperature. A number of different theoretical models are available to mathematically describe the particle drop shape that influences attenuation estimation. Each of these models has proven effective in different scenarios. It can be difficult, however, to predict which theoretical model to use. The total differential phase gives an idea of the attenuation, but it depends on the model. Moreover, the total attenuation along a rain path must be apportioned to different parts of the radar path in order to correct for attenuation along a radar path. Embodiments of this invention allows for a system to apportion the attenuation to different parts of the radar beam. Embodiments of the invention also allow for optimization of a number of different theoretical models for both drop size and temperature.
