波瓣區
英文
lobe region-
On the base of above it, this paper discuss the synthesis of optimum distributed arrays by nonuniform spacing in the sense of dolph - chebyshev. having derived the equations of optimum element distribution, we analyze the exponentially spaced array, which are optimum when the elements are isotropic and equally weighted, and the array by general raised cosine function. the formulate for estimating the sidelobe envelope, beamwidth of the array pattern and clean region width are obtained
推導了最佳陣元分佈方程，分別對陣元無方向性和等加權時的最佳分散式陣列? ?指數間隔陣列和採用廣義升餘弦加權的最佳分散式陣列進行了分析，推導了天線方向圖旁瓣包絡、波束寬度，干凈掃描區寬度的估計公式，給出了近軸旁瓣電平與陣列參數的關系。In the chapter, we are also presented a low sidelobe beamforming synthesis technique. the main beam is pointed in the proper direction by choosing the steering vector for that direction
為了獲得自適應優化權向量，形成任意的旁瓣電平波形，即使在旁瓣區域干擾很強時，也能保證有很好的方向圖輸出。This paper introduces principle of fractal and the mandelbrot fractal theory. it analyze the fractal character and study the mltifractal for the clutter tracking. in according to the rage which follow the q on point fractal dimension and region fractal exponent. we confirm the prepreerence multifractal high moment, combining the clutter feature of pd radar and novel multifractal approach, the mainlobe clutter tracking come true
