摘    要:根据干扰器对抗主动声纳的机理和水声干扰方程,针对干扰器与舰艇目标在同一位置和不在同一位置两种配置,分别提出了干扰器有效干扰压制区域的计算方法,其中第二种配置下包括了声纳波束主瓣对准目标和主瓣对准干扰器这两种情况。以对抗平面阵声纳为例,给出了特定态势下主动声纳波束主瓣和旁瓣受干扰情况下的有效干扰压制区域。仿真结果表明,有效干扰压制区域的大小与噪声干扰器和声纳的性能以及对抗态势等因素有关,声纳波束主瓣受干扰时有效干扰压制区域较大,效果较好。

关 键 词:水声对抗  噪声干扰器  有效干扰压制区域  主动声纳  方向特性函数  水声干扰方程

Abstract:Based on the jamming mechanism of noise jammer against active sonar and the underwater acoustic jamming equation, the calculation of the effective jamming suppressing zone (EJSZ) of noise jammers is proposed when jammer and target are in the same position as well as are not in the same position, and the latter configuration includes two different situations, namely aiming the sonar beam main lobe at the target and the noise jammer, respectively. To counter the planar array active sonar, for example, the EJSZ of the sonar beam main lobe and side lobe interfered by the noise jammer is presented under a certain situation. The results show that the EJSZ is related to the performance of the noise jammer, active sonar and their relative position, and the EJSZ is more bigger when the sonar beam main lobe is interfered by the noise jammer.
