Based on instrumental sensors, a cascade calibration method of the near-field source is proposed. The method can not only uses multiple independent near-field signals operating at different times and different locations calibrate the gain and phase errors and position errors, but also locate the near-field source at the same time. At the single signal, reconstructing the virtual array and steering vector transformation are taken. Compared to the joint estimation of multidimensional parameters, the method can be estimated in real time and less affected by error variations. Only one-dimensional spectral search is needed and there is no loss of aperture in constructing the virtual array. Simultaneously, simulation experiments show the performance of the proposed algorithm in this paper.

A novel high degree of freedom sparse array with displaced multistage cascade subarrays
AbstractThe coprime array is a recently developed sparse array that is widely used in direction-of-arrival (DOA) estimation. The degree of freedom (DOF) for existing coprime arrays relies on the virtual array model, which is limited to the ...
