| 为解决预警雷达作战效能评估中兼顾高精度和高时效性的难题，提出了精细化功能级仿真建模方法。其中，检测处理子模型严格计算雷达系统、阵地地形、目标运动、目标RCS起伏、电子干扰等影响，精确计算目标信干噪比和检测概率，以逼近信号级仿真模型的精度生成点迹数据；点航迹处理子模型按照实装软件完成虚假点迹过滤、点迹凝聚、航迹起始、点航迹关联、航迹滤波等处理；行为控制模型按照实装规则执行干扰环境感知与抗干扰控制策略。相比传统功能级仿真方法，本方法可更为准确模拟复杂环境下的雷达抗干扰性能。 |

| Abstract: |
| In order to achieve both high precision and high efficiency for the radars’ operational effectiveness evaluation, the paper proposes a refined functional simulation method. The radar detection processing model strictly imports the influences of radar system, site elevation, target motion, RCS fluctuation, electronic jamming, etc., then precisely calculates targets’ SINR and detection rate, and finally generates the plot data whose precision approaches the signal?level simulation models. The plot?track processing model performs false detection reduction, plots centroid, track initialization, plot?to?track association, and track filtering in compliance with realistic software. The radar behavioral model implements the jamming recognition and anti?jamming strategies in compliance with actual rules. Comparing with traditional functional simulations, the method in this paper can accurately simulate the anti?jamming performance under complicated environment. |
