摘　　要：高速数字信号处理的快速发展使得现代相控阵雷达自适应旁瓣对消(ASLC)系统可实现边采样边对消,传统基于干扰时间常数和对消时间常数的干扰方式不再奏效。从相控阵雷达ASLC的基本原理和权值优化算法出发,仿真分析了ASLC系统的抗干扰性能,基于相控阵雷达信号检测流程和样本选取原则,采用前导灵巧噪声干扰方式,以补偿干扰反应时间,使干扰信号在时域上完全覆盖真实目标信号,破坏ASLC系统的干扰样本选取,仿真结果表明了该方法的有效性。With the rapid development of high-speed digital signal processing, cancellation while sampling can be realized by the adaptive sidelobe cancellation(ASLC) system of modern phased array radar. The traditional jamming method based on jamming time constant and cancellation time constant is no longer effective. Based on the basic principle and weight optimization algorithm of ASLC of phased array radar, the anti-jamming performance of ASLC system is simulated and analyzed. Based on the signal detection process and sample selection principle of phased array radar, the leading smart noise jamming is adopted to compensate the jamming response time, so that the jamming signal completely covers the real target signal in the time domain and destroys the jamming sample selection of ASLC system. Simulation results show the effectiveness of the method.
