ABSTRACT: In high frequency surface wave radar (HFSWR) applications, range and azimuth resolutions are usually lim-ited by the bandwidth of waveforms and the physical dimension of the radar aperture, ...

Abstract: In this paper, the reconstruction method for the element pattern of the antenna arrays is introduced. The reconstruction method can be employed to calibrate the mutual coupling in the data ...

Abstract: The sparse array technique is an excellent approach to tackle the connection difficulties due to the huge number of elements of 2D matrix arrays. However, the reduction of the element number ...
