摘要： 融合发现概率是警戒雷达网的一项重要战术指标，但该指标对指挥员来说难以理解和运用。针对该问题，提出一种基于等值线填充的融合发现概率可视化方法。给出战场任意区域的空间点采样方法，建立目标融合发现概率的计算模型，设计等值线填充时非闭合等值线的闭合处理算法和相邻等值线间的区域提取算法。对3部雷达构成的雷达网在无干扰和有干扰下的融合发现概率进行可视化分析，实验结果表明，可视化后的融合发现概率图直观、形象，指挥员可以掌握警戒雷达网任务区域内任意位置的发现概率，以及雷达网受到干扰后融合发现概率的变化情况。

Abstract: Fusion Detection Probability(FDP) is an important tactics index for radar net, but it is difficult comprehension and usage to commander. In order to solve this problem, this paper puts forward a visualization method based on contour line filling. Sampling algorithm of arbitrarily battlefield district is presented, calculation model for fusion detection probability of the sampled spatial spot is built, the algorithm of a non-close curve changing to closed curve and the region extraction between two equivalent lines next to each other are designed. In the condition of no jamming and with jamming, it analyzes the FDP’s visualization results of radar net which composes of three radars. It is proved that the results of FDP are very visualization. Commanders can master the radar’s detection probability for arbitrarily position in the radar’s task region, also they can know the change of FDP when the radar net is jammed.
