| 摘 要： | 自适应波束形成(ADBF)和自适应旁瓣对消算法都能够很好地抑制旁瓣干扰,但是由于干扰协方差矩阵的影响,ADBF在抑制干扰同时给和、差单脉冲测角带来误差.文中针对自适应旁瓣对消算法,系统研究了其在和、差单脉冲测角中的应用,着重分析了辅助天线中的目标信号对测角性能的影响.理论分析和仿真结果表明,辅助天线中的目标信号对测角的影响主要存在于辅助天线的增益大于差波束增益的角域,而在其他角域,影响很小.

| Abstract: | Adaptive beam forming (ADBF) and adaptive side lobe cancellation can effectively suppress the jammer,but because of the influence of the jammer covariance matrix,error is introduced in the monopulse estimation when ADBF is used. The application of adaptive side lobe cancellation in monopulse angle estimation is systematically studied in this paper,The influence in the performance of angle estimation of target signal in the auxiliary array is analyzed. Theoretic analysis and simulation result shows that the ... |
