A frequency domain radar interferometric imaging (FII) technique based on high-resolution methods

摘要: Abstract In the present work, we propose a frequency-domain interferometric imaging (FII) technique for better knowledge of vertical distribution atmospheric scatterers detected by MST radars. This is an extension dual interferometry (FDI) to multiple frequencies. Its objective reduce ambiguity (resulting from use only two adjacent frequencies), inherent with FDI technique. Different methods, commonly used in antenna array processing, are first described within context application FII These methods Fourier-based imaging, Capon's and singular value decomposition method MUSIC algorithm. Some preliminary simulations tests performed on data collected middle upper atmosphere (MU) radar (Shigaraki, Japan) also presented. work step developments which seems be very promising.
