This paper present a solution for detecting hidden objects based on UWB pulse radar. In this paper, we introduce an overview of UWB systems, the theory related and used in the process to implement the project. We present the steps to collect and process data through object identification algorithm, improve algorithm for detecting hidden objects in some kind of environments. We evaluate the obtained results, conclude for applying orientation and development of the subject.

Serpentinite of Hiep Đuc complex has been determined and described in project of geological mapping in 1/ 500,000 scale and arranged in hyperbazite formation with MgO/ FeO > 6 (Huynh Trung et all, 1980). They are lens, sheet in shape, with small crops. They injected along tectonic line (rift) with longitudinal direction or subparallel direction. They do not cause thermal - exomorphism for surrounding rocks and named as non root – protrusion. Petrography composition are mainly olivinite, lherzolite (chemical composition) rich in MgO (32–37%). The serpentinite bodies distributed mainly in rift zone. This zone displays spilite and ultramafic, mafic formations of Ngoc Hoi complex of early Paleozoic age. Serpentinite formations of Hiep Duc complex are not common magmatic origin of spilite, pyroxenite, gabbro formations which mentioned. Association of these formations formed Kontum ophiolite assemblage of early Paleozoic age, which can be compared with ophiolite assemblage of Alpine-type.Petro-geochemical characteristic of serpentinite are like composition of upper mantle, alpinotype hyperbazite and oceanic floor. During early Paleozoic, they were compressed and protruded from deep crush. Kontum massif was formed in late Proterozoic, and separated into microplates by tectonic line in which the serpentinite bodies of Hiep Duc complex protruded.

The first time, Xuanthu granitoid massif was researched and arranged into component of Bana complex in project of 1/50,000 scale geological mapping and minerals prediction of Quangngai sheets (Than Duc Duyen et al, 1999). The investigations carried out within area of Nuocnhieu stream, SE corner of Xuanthu massif which has displayed mainly plutonic formations, such as biotite granite, medium - coarse granular 2 mica granite, fine granular granite and fine granular 2 mica granite. Vein phases are commonly aplite, pegmatoid, porphyry granite.... This paper is mainly to research on mineral - petrography and petro - geochemical characteristics as well as to make more clearly about material component, mineral forming order, forming original explaining and related mineralizations of Xuanthu granitoid massif.
