“Method of Eliminating Ground Echoes for a Meteorological Radar” describes a way to distinguish ground echoes from other radar returns. The method calculates a spatial statistical parameter for echoes received across distance cells and compares how that parameter varies along an analysis path. Echoes are classified as ground echoes when the variation exceeds a predetermined threshold.

“Method of Determining the Velocity Field of an Air Mass by High Resolution Doppler Analysis” presents a spectral-analysis approach for examining radiofrequency signals sampled by meteorological radar. It uses a trellis autoregressive Burg algorithm to estimate signal frequencies for each distance cell. Regularized reflection coefficients help limit numerical instability and determine the model’s effective order, while the resulting analysis identifies natural frequencies used to assess air-mass movement.

Career Highlights

Chaure’s listed patent work focuses on radar signal analysis and meteorological applications. The inventions address two related challenges: separating ground clutter from radar observations and extracting information about air-mass velocity from Doppler signals. His association with Thales places this work in the context of a company active in technology and engineering.
