【摘要】 抗干扰能力是雷达的一项核心战术指标,而由于现代战争中电磁环境日益复杂,雷达抗干扰面临越来越多的挑战。本文提出一种基于数字阵列雷达体制的自适应-自适应(Adaptive-Adaptive,AA)的抗干扰方法,该方法可有效抑制副瓣来向干扰,同时还可显著改善因干扰样本中混入目标信号而导致的目标相消问题,具有较高的工程应用价值。仿真实验验证了该方法的有效性。更多还原

【Abstract】 Anti-jamming capability is a key tactical specification of radars. The electromagnetic environment is becoming more complex in modern war,anti-jamming for radar will face more challenges. An adaptive-adaptive( AA) based adaptive anti-jamming approach for digital array radar is proposed; it can effectively suppress jamming from sidelobe. Meanwhile,the target cancellation due to jamming signals mixing in target signals can be prevented.Simulation results show the effectiveness of the novel method.更多还原
