摘要

摘要: 針對大角度覆蓋范圍目標快速定位以及機動目標精確角度跟蹤的需要，該文提出一種基于可控測角精度和范圍的數(shù)字陣列單脈沖和差波束迭代快速優(yōu)化算法。算法可以根據(jù)期望的測角精度或期望測角區(qū)間，以函數(shù)形式給出修正的期望和差波束方向圖主瓣區(qū)域，然后采用所提出的快速區(qū)域加權方向圖綜合算法閉式優(yōu)化得到和差波束方向圖。該算法通過迭代優(yōu)化可以在給定輸入信噪比和測角精度需求的前提下，最大化單脈沖角度估計的有效測角區(qū)間，或者在給定的測角范圍內，最優(yōu)化測角精度。

Abstract: A fast iterative optimization algorithm for sum and difference patterns with controllable accuracy and range of angle measurement is proposed, which can be used in fast targets location under wide angle coverage and accurate angle tracking of maneuvering targets. Under expected accuracy or range of angle estimation, the expected main-lobe of sum and difference patterns are modified in the form of sinc function and its derivative respectively, then the sum and difference patterns are rapidly synthesized with the proposed regional weighting pattern synthesis algorithm in the close form. The proposed iterative optimization algorithm can effectively maximize the range of effective angle measurement at a given input signal to noise ratio and angular accuracy, or get optimal accuracy within a given range of angle measurement.
