En el artículo se comparan el campo reflejado y la SED que se obtienen por medios analíticos y mediante la simulación. Inicialmente el análisis se realiza para un objeto en forma de cilindro embebido en un medio homogéneo. Posteriormente, la simulación se aplica a objetos con distintos tamaños, formas y materiales sobre la superficie del mar, por lo que el sistema constituye un medio heterogéneo debido a la frontera mar - aire. La confirmación de la posibilidad del empleo exitoso de la simulación numérica a este caso constituye el principal objetivo del trabajo. Para la simulación se ha utilizado el sistema de programas CST Microwave Studio (CSTME) y con este fin se ha investigado su aplicación al caso mencionado. Con los resultados obtenidos se confirma que su solución nos facilita la principal tarea a resolver: la valoración del nivel de retrodispersión desde estos objetos sobre el mar a través de la SED y el campo eléctrico obtenido en cada caso. Estos resultados dan la posibilidad práctica de la identificación o el reconocimiento de cada blanco por el tipo de material, forma y tamaño.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Target recognition of small and slow radar targets with low Radar Target Cross Section (RTCS) on the sea surface is a very important matter in coastal radar field. This article presents a comparative study of the scattered field and the RTCS obtained by analytical means and from computationally simulated small cylindrical radar targets, initially in a homogeneous medium. The forward analysis is based on the simulation of small objects of different sizes, shapes and materials over the sea surface. In this condition, present environment is a heterogeneous medium, the sea - air frontier. The confirmation of the possibility of successful use of numerical simulation in this case is the principal objective of this work. The CST Microwave Studio software programs are used for the simulation; its analysis has required a detailed research over the application of CST in this problem. The obtained results confirm that its solution is the principal task to resolve and to obtain the level of RTCS and field scattering of these objects over sea in each case. Results give us, also, the practical possibility of recognition or identification of each target from the type of material, shapes and sizes of objects.]]></p></abstract>
