A method for electromagnetic radiation source identification is proposed. The spatial characteristic of a radiation source is taken as the unique parameter for support vector machines (SVMs) to identify. First, the location of radiation source is determined by the triangulation method, and then its spatial characteristic is collected by a band receiver array with simulation, which removes the limit...
This paper analyzes different spatial distribution of the field strength in the far field of different antenna. We will receive the field strength in the same area by receiving array based on directional diagram, and then send the data to BP neural network to simulate the nonlinear features of different antenna modeling so as to achieve the classification of different antenna. At last we will compare...
A new terrain meshing method based on the ray-tracing algorithm is presented. In the propagation model, most of the transmission paths are focused in the area that between the transmitters and receivers. The main idea is to mesh the area containing both the transmitters and receivers into fine triangles while the rest area into larger triangles. The processing time of this developed method is half...
In most test analysis, we always want to construct a parameter model, and then through sample statistics and model parameters, we can get the properties, or characteristics of what we concern about. Confidence intervals can give an estimate of the range within which the true value of the statistic lies. And a narrow confidence interval indicates the low variability of the statistic, which can give...
