Abstract

A radar adopts anti-jamming techniques such as side lobe cancellation and moving target indication, resulting in the worsening of the effects of single active jamming and passive jamming. Therefore a compound jamming strategy was proposed and can effectively respond to the anti-jamming device of the new radar. The conditions for the use of this strategy were defined. Based on the military airspace planning principles, taking into account human error, wind and other errors, the specific process of airspace planning was elaborated. Taking into account the effects of compound jamming and the safety of a jammer, an airspace model for stand-off and compound jamming was established. The Whale Optimization Algorithm (WAO) with Tent chaotic sequence was used to solve the model and the airspaces with different preferences were planned. The simulation results show that the model is scientific and effective. The optimization ability of the WOA of with tent chaotic sequence is better than WAO. In addition, the planning direction is quite different in Simulation 1 and Simulation 2, with a maximum of 99°. The compound jamming for stand-off jamming in airspace planning is more flexible and has more advantages in multiple military planning airspaces.

摘要

由于雷达采用旁瓣对消以及动目标显示等抗干扰技术，导致单一有源干扰和无源干扰效果变差，提出一种复合干扰策略，该策略能够有效应对新体制雷达的抗干扰技术，并且对该策略使用的条件进行了限定说明，依据军事空域规划的原则，考虑人为误差、风等误差因素等影响，阐述了空域规划的具体流程，考虑复合干扰效果和干扰机的安全，建立了远距离支援复合干扰的空域模型。采用Tent混沌序列的鲸鱼优化算法对其进行解算，对不同偏好下的空域进行了规划，与原始的鲸鱼优化算法相比，其寻优效果更好，同时仿真结果表明所建的模型是科学有效的，在仿真1和仿真2中，所规划的空域方向差异较大，最大可达99°，这表明运用复合干扰策略的远距离支援干扰空域规划较为灵活，在规划多个军事空域时对其他空域的限制性小。
