AI Technical Summary
Existing detection methods cannot obtain the moisture distribution inside corn ears in a non-destructive, layered, and accurate manner. Traditional far-field microwave imaging methods are limited by the Rayleigh diffraction limit, resulting in low resolution, severe multipath effects, and large computational load for inversion.
By employing a microwave near-field imaging method, which utilizes multi-frequency microwave signals to receive evanescent wave components, and combining multi-polarization technology with nonlinear optimization algorithms, the geometric contour and dielectric constant distribution of corn ears are inverted to achieve layered imaging.
It achieves non-destructive, layered, and high-precision detection of moisture inside corn ears, breaking through the diffraction limit and improving spatial resolution and imaging accuracy.
