dc.description.abstract | We have implemented an eight-antenna module configuration at Jicamarca, to perform a three-dimensional imaging of the atmospheric brightness distribution, particularly at tropospheric (7 to 12 km) and E region heights (95-105 km). Four different methods have been implemented to solve for the inverse problem, i.e., to get the atmospheric brightness from visibility samples on the ground. We have used a Fourier-based, Capon and Maximum Entropy (MaxEnt) methods. In addition, we have implemented a fitting technique where a brightness distribution, characterized by a number of anisotropic Gaussian blobs, is assumed. It is important to note that with our current configuration we can characterize up to six anisotropic Gaussian blobs. These four methods are compared using experimental and model data. For the experimental part, we have taken advantage of the good knowledge that we have on the mean position, orientation and aspect sensitivity of the equatorial electrojet (EEJ). | es_ES |
