摘要
研究了稀布阵雷达抗干扰机理,分析了传统基于维纳霍夫方程的副瓣对消算法和基于数字波束形成的新型自适应副瓣滤波算法,对比了2种算法在稀布阵雷达中应用的优缺点,总结了影响副瓣对消性能的因素,并通过实测数据验证了2种算法的副瓣干扰对消性能。结果表明,相对传统副瓣对消方法,新型副瓣对消方法性能更加稳健,更适用于稀布阵雷达。
This paper studies the anti-jamming mechanism of sparse array radar,analyzes the traditional side-lobe cancellation algorithm based on Wiener Hoff equation and the new-type adaptive side-lobe filtering algorithm based on digital beamforming,compares the advantages and disadvantages of two algorithms applied to sparse array radar,and summarizes the factors affecting the performance of side-lobe cancellation.The side-lobe interference cancellation performance of two algorithms is verified through the measured data.The results show that new-type side-lobe cancellation method has more robust performance and is more suitable for sparse array radar compared with the traditional side-lobe cancellation method.
