摘要:

电磁环境适应性试验是装备作战运用的重要参考。针对雷达对抗装备电磁环境适应性考核评估需求,根据其典型作战任务,梳理了试验环境需求,提出了在试验中电磁环境构设的基本方法。构建了电磁环境适应性评估指标体系,并分析了电磁环境对雷达对抗装备的信号截获概率、侦察距离、分选识别的影响,在计算电磁环境对雷达对抗装备侦察距离影响时,将干扰能量视为接收机噪底,利用自由空间距离公式计算得到了干扰情况下侦察距离公式,并进行了仿真验证。仿真结果表明,侦察天线越对准干扰源,侦察距离降低越明显。最后,综合考虑不同电磁环境复杂度作战影响和电磁环境适应情况,提出了电磁环境适应性评估方法,并用实例说明了评估方法的可行性。

Abstract:

The electromagnetic environment adaptation test is an important reference for equipment operation application. In view of the requirements of the electromagnetic environment adaptation test and evaluation for radar countermeasure equipment, this paper untangles the test environment’s requirement based on the typical operation mission of the equipment, proposes the basic method for constructing the electromagnetic environment in the test, establishes the adaptation evaluation index system, and analyzes the effects of the electromagnetic environment on the signal intercept probability, reconnaissance range, and sorting and identification. In the calculation of the influence of the electromagnetic environment on the reconnaissance range of radar countermeasure equipment, the energy of jamming signals is considered as reconnaissance’s noise, and the distance formula in free space is used to derive the reconnaissance range formula under jamming, which is then verified by simulation. The results show that the significant decrease of reconnaissance range is associated with the alignment between reconnaissance antenna and interference source. Integrating the operation influence of the different complexity of electromagnetic environment with adaptation status, this paper proposes a method for electromagnetic environment adaptation evaluation and shows the feasibility of the method by an example.
