摘　　要：空间分布的宽带多干扰源会掩盖被动声纳系统对目标辐射噪声的接收,形成干扰抑制区域,降低系统的有效探测范围和探测精度。论文从被动声纳方程出发,利用宽带阵列信号处理方法,仿真舰艇辐射噪声、海洋环境噪声和宽带干扰源信号,得出了有指向被动声纳系统在多干扰源场景下的有效探测范围,分析了多干扰源对系统目标方向输出信号波形和系统方位估计性能的影响。The collection of target-radiated noise for passive sonar can be effected by broadband multi-jammers which distributed spatially,the detection range and accuracy will be reduced as a result of the appearance of jammer suppression area.In this paper,with the help of passive sonar equation and the theories of broadband array signal processing,the ship-radiated noise,ocean ambient noise and broadband jammer signal are simulated to deduce the effective detection range of directional passive sonar system under multi-jammers,the direction of arrival and the output signal of passive sonar system are also discussed.
