“…The correct DEMs are necessary for geological, mining detections in spite of the negative aspects of synthetic aperture radar records due to speckles and object geometry distortions. Lopes et al, 5 Touzi, 6 Yu & Scott, 7 Hondt et al, 8 Helmy & El-Taweel, 9 Marghany, 10 Marghany [10][11][12][13] Recently, Marghany 14 developed a new technique for geological, mining detection in TerraSAR-X based Particle Swarm Optimization (PSO). In this view, Marghany 14 and Marghany 15 mentioned that Particle Swarm Optimization has accurate performance in solving several single and multi-objective optimization noises in TerraSAR-X data, such as noise despeckles, which approved by Riccardo et al, 16 and Jin et al 17 This optimization of SAR speckles might produce high target visibility in coherence data.…”
