This paper presents a multi-frequency method to increase the number of incoherent sources that can be resolved using MUltiple SIgnal Classification (MUSIC). The method uses coarray equivalence to construct a “virtual correlation matrix” with a higher dimension than the number of receiving elements. This allows for more sources to be resolved(More)
We explain how multiple frequencies can be used to extend the capabilities of the spectrum estimation method for high-resolution location of multiple non-coherent point sources. The techniques covered in this paper are MUltiple SIgnal Classification (MUSIC), Autoregressive (AR) spectrum estimation and Capon minimum variance spectrum estimation. Our approach(More)
We present a method to improve high-resolution imaging of coherent point reflectors with transmit/receive arrays. The data obtained from the array can be rearranged into a virtual data matrix to resolve additional reflectors. The problem with using a virtual array is that it may not necessarily be able to resolve coherent reflectors due to a rank deficiency(More)
