摘要:

雷达导引头采用动目标显示、边搜索边跟踪等抗干扰技术, 导致传统质心、冲淡、幕墙式箔条干扰方法干扰效能降低。对此,提出一种机动化箔条幕布放方法, 通过无人机和舰船协同布放箔条弹, 使幕墙能量质心随时间不断移动, 保证舰船在有效时间内成功逃离雷达波束。首先, 基于机动化箔条幕干扰机理, 构建箔条幕布放模型, 具体包括雷达导引头运动模型、舰船运动模型、箔条幕形态模型和箔条幕运动模型。随后, 根据机动化箔条幕模型求解特点, 确定采用布谷鸟搜索算法求取布放方案;据此提出总体求解思路, 并构建布放效能条件(目标函数与约束条件); 采用Logistic混沌机制改进布谷鸟搜索算法, 建立补弹策略。最终, 通过仿真案例对机动化箔条幕布放模型的有效性进行分析验证。结果表明, 与常规箔条幕布放方法相比, 机动化箔条幕布放方法能够有效减小舰船逃逸时间, 降低箔条弹消耗量, 同时具备较强的应对不同风速风向的能力。

Abstract:

The radar seeker adopts anti-interference technologies such as moving target display and tracking while searching, which leads to a decrease in the interference efficiency of traditional centroid, dilution, and curtain wall style chaff interference methods. A motorizedchaff screen deployment method is proposed to ensure that the energy center of the curtain wall moves continuously over time by coordinating the deployment of chaff bullets by drones and ships, ensuring that the ship successfully escapes the radar beam within an effective time. Firstly, based on the mechanism of motorized chaff screen interference, a chaff screen deployment model is constructed, which includes a radar seeker motion model, a ship motion model, a chaff screen shape model, and a chaff screen motion model. Subsequently, based on the characteristics of the motorized foil curtain model, it is determined to use the cuckoo search algorithm to obtain the deployment plan. Based on this, propose an overall solution approach and construct deployment efficiency conditions (objective function and constraint conditions). Using logistic chaos mechanism to improve the cuckoo search algorithm and establish a replenishment strategy. Finally, the effectiveness of the motorized chaff screen deployment model is analyzed and verified through simulation cases. The results show that compared with conventional chaff screen placement methods, motorized foil screen placement methods can effectively reduce ship escape time, reduce chaff cartridge consumption, and have strong ability to cope with different wind speeds and directions.
