摘　　要：有源噪声干扰是一种通用的雷达和通信干扰方式。提出了一种基于OFDM的多载波调制宽带有源噪声干扰信号产生方式,具有比传统单载波调制方式更好的遮盖性能,并且能够实现更加灵活的干扰频带控制,适应多目标同时干扰的要求;仿真也验证了方法的优越性。Active noise jamming is a widely used radar and communication jamming mode. In this paper a wideband active noise-jamming signal generation method is proposed based on OFDM with multi-carrier modulation. Compared with the traditional single-carrier modulation, the proposed method has much better barrage jamming performance. With this method, the frequency band distribution can be more flexiblely controlled to realize simultaneous multi-target jamming. The simulations also demonstrate the advantage of the propesed method.
