Antenna as a spatial energy converter and airspace radar signal processor is one of the important and indispensable subsystem array antenna technology is the key to the spatial domain signal processing techniques . Array signal processing main areas of research can be divided into beam forming technology, space technology and zero spectrum estimation techniques and other aspects , they are based on spatial sampling of the signal data processing . Among them, the beamforming array antenna by adjusting the excitation of each element , so that the antenna beam pattern into the specified beam shape , spatial spectrum estimation main research directions for super-resolution direction estimation , zero technology mainly in the beam conformal zero point of the antenna under the alignment direction of interference . Practice has proved that these types of technologies can improve spatial array antenna signal processing performance . This paper first introduces the basic phased array antenna theory , array signal processing techniques for the study of the foundation ; Then study the phased array antenna pattern narrow beam , low sidelobe design methods, linear array synthesis method , the main research of Taylor Comprehensive France and Chebyshev synthesis method , in a flat array pattern synthesis method, a rectangular array of law and the separation of the annular aperture synthesis method sidelobes , meanwhile, proposed a linear least squares method and integrated method to achieve a comprehensive array of uniform ring algorithm ; then study the spatial decomposition based on feature -MUSIC spectral estimation algorithm algorithm, based on this study the two-dimensional space-time signal model based on the frequency - DOA dimensional spectral estimation algorithm , while using spatial smoothing technique to achieve a coherent signal finding the source of super-resolution frequency measurement ; Finally, the study zero technique proposed method and the preset zero phase shift method to meet the conditions of the beam conformal array antenna pattern to achieve the zero setting .
