潜用干扰器对抗舰艇主动声探测的建模及仿真

目前在使用噪声干扰器进行仿真时，声纳波束旁瓣对干扰器干扰效果会产生影响，而且在水面舰艇和潜艇的机动中一般使用平均加速度旋回模型或者先旋回后加速模型，准确度不高，本文针对以上问题，在仿真过程中增加了声纳旁瓣对噪声干扰器的影响，改进了水面舰艇和潜艇的机动模型，增加了潜艇变速过程中的电量消耗模型，并把潜艇的对抗时间和电量作为衡量指标，搭建了潜用干扰器对抗舰艇主动声探测仿真的框架，设计了仿真流程，仿真结果与已有试验数据相符。

Modeling and Simulation of Submarine's Noise Jammer Countering Detection of Surface Ship's Active Sonar

To reduce the influence of sonar beam sidelobe on interference effect of noise jammer, and improve the accuracy of the average acceleration turning model and the turning before acceleration model, which are adopted in the process of elusive maneuver of surface ship and submarine, we consider the influence of sonar beam sidelobe on noise jammer in simulation, improve the maneuver models of surface ship and submarine, add the model of battery capacity consumption during submarine speed variation, and simulate the process of submarine＇s noise jammer countering detection of active sonar by taking the countermeasure time and battery capacity as weighing indexes. Simulation results are consistent with test data.
