摘要：
Two-dimensional (2D) gold multiple signal classification (gold-MUSIC) is proposed in order to reduce the complexity of MUSIC and make real-time processing possible for joint range and angle estimation by multi-carrier frequency multiple-input multiple-output radar. 2D gold-MUSIC evaluates the MUSIC spectrum at coarse intervals, then determines peaks by narrowing the 2D search area iteratively based on a simultaneous gold-section of range and angle to find accurate localisation of the peaks. The proposed method eliminates huge computation burden caused by a grid-by-grid spectral search of classical MUSIC and obtains remarkable resolution in range and angle with no dependence on array configurations. Numerical studies demonstrate the effectiveness and efficiency of the proposed method.
