  • 摘要: 該文研究了共形稀疏陣列在艇載外輻射源雷達中的應(yīng)用問題，并分析了艇載外輻射源雷達目標(biāo)探測性能。鑒于天線在雷達系統(tǒng)中的重要地位，重點分析了稀疏陣列數(shù)字波束形成(DBF)天線的布陣方式及天線方向圖指標(biāo)?；诮M合巴克碼實現(xiàn)艇身稀疏陣列共形布設(shè)，提出一種曲線陣列到直線陣列的補償方法，以獲得理想的DBF天線方向圖。針對曲線陣列可能存在的形變問題，采用分布式位置和姿態(tài)測量系統(tǒng)(POS)進行形變誤差測量，經(jīng)曲線擬合后實施精確補償。仿真結(jié)果表明所提方法的有效性。
    Abstract: The application of conformal sparse array to airship-borne passive radar is studied, and the target detection performance of airship-borne passive radar is analyzed. Because of the importance of antenna in radar system, embattle method of sparse array Digital Beam Forming (DBF) antenna and antenna pattern index are selectively analyzed. Layout of airship-borne sparse array is implemented based on the combination of Barker code. In order to obtain ideal DBF antenna pattern, a method of compensating the curve array to the linear array is proposed. With respect to the possible deformation problem, the distributed Position and Orientation System (POS) is used to measure the deformation error based on which curve fitting is implemented to conduct accurate compensation. Simulation results show the effectiveness of the proposed method.
