摘要

The present invention relates to a method of obtaining optimal contrast in a polarized synthetic aperture radar (SAR) image, comprising: a first step of determining a target and a clutter, and then selecting a learning region in both the determined target and clutter; A second step of calculating a covariance matrix for the target and clutter by averaging the learning region; A third step of taking the contrast ratio in the second step and maximizing the contrast ratio using the Lagrange multiplier technique; And a fourth step of obtaining a transmitted / received polarized light corresponding to the maximum contrast in the third step and synthesizing a new optimal contrast image using the polarized light. The method of acquiring an optimal contrast in a polarized synthetic aperture radar (SAR) Thus, the optimal contrast can be obtained by using the covariance matrix calculation and the Lagrange multiplier technique for the learning region of the target and the clutter, so that the target can be accurately recognized, and even in the case of multi-channel and multi-frequency data There is an effect that can be applied.
