针对通信、雷达等用频装备日益突出的电磁频谱使用安全,以及电磁频谱参数泄露风险量化评估难等问题,本文采用数值、解析等方法对敌我用频装备发射特征、接收敏感特征及天线辐射特性等进行电磁特征参数建模;结合电磁频谱参数泄露完整的通信链路结构,从用频装备效能与电波环境影响角度进行分析,运用网格剖分思想,量化分析用频装备电磁频谱参数泄露概率,提出一种电磁频谱参数泄露概率计算方法,并通过仿真验证了该计算方法.计算得到地面固定雷达L1和1 000跳发射电台M1分别在300～450 km和350～450 km范围内的泄露概率值,实现了电磁频谱参数泄露风险量化评估,解决了电磁频谱参数泄露风险量化评估难问题.
Abstract
In response to the increasingly prominent issues of electromagnetic spectrum usage safety for communication and radar equipment,as well as the difficulty in quantifying the risk assessment of electromagnetic spectrum parameter leakage,this paper employs numerical and analytical methods to model the electromagnetic characteristic parameters of emission features,reception sensitivity,and antenna radiation characteristics for both friendly and adversary frequency-dependent equipments.By integrating the complete communication link structure of electromagnetic spectrum parameter leakage,the analysis is conducted from the perspectives of equipment effectiveness and the impact on the radio wave environment.Utilizing the concept of grid division,a method for calculating the probability of electromagnetic spectrum parameter leakage is proposed,and the calculation method is verified through simulation.The leakage probabilities for a ground-based fixed radar L1 and a 1 000-hop transmission station M1 within the ranges of 300～450 km and 350～450 km,respectively,are calculated.This achieves a quantified assessment of the risk of electromagnetic spectrum parameter leakage,solving the problem of difficult risk quantification in electromagnetic spectrum parameter leakage assessment.
