摘　　要：抗干扰能力是雷达的一项核心战术指标,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。提出一种基于数字阵列雷达体制的自适应-自适应(AA)的抗干扰方法,该方法可有效抑制副瓣来向干扰,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。仿真结果验证了该方法的有效性。The anti-jamming ability is a key tactical index for radar.Because the electromagnetic environment becomes more and more complex in modern war,more and more challenges are confronted with the radar anti-jamming.This paper puts forward an adaptive-adaptive（AA）anti-jamming method based on digital array radar system.The method can effectively suppress the jamming from side lobes,and can evidently improve the target cancellation problem due to the mix of jamming signals and target signals,has higher engineering application value.The simulation result validates the validity of the method.
