| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | CCD(Coherent Change Detection) is one of techniques that detects changes between SAR image pair. In this averaging process, the coherence value decreases by increasing window size. The dinamic range of coherence value changes by the number of pixel. In this report, we propose a method of an adaptive averaging process using Lee Filter that changes window shape while keeping resolution. A pseudo covariance matrix is used for the coherence optimization. As a result, the precision enhancement over the conventional method is confirmed. The data is obtained by Ku-band FM-CWPOLSAR in an anechoic chamber. | |
