基于共形稀疏阵列的艇载外辐射源雷达性能分析
|
摘要
该文研究了共形稀疏阵列在艇载外辐射源雷达中的应用问题,并分析了艇载外辐射源雷达目标探测性能。鉴于天线在雷达系统中的重要地位,重点分析了稀疏阵列数字波束形成(DBF)天线的布阵方式及天线方向图指标。基于组合巴克码实现艇身稀疏阵列共形布设,提出一种曲线阵列到直线阵列的补偿方法,以获得理想的DBF天线方向图。针对曲线阵列可能存在的形变问题,采用分布式位置和姿态测量系统(POS)进行形变误差测量,经曲线拟合后实施精确补偿。仿真结果表明所提方法的有效性。
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.
