空间多目标空域分布分析及解算方法

Description and Calculation of Multi-Target Spatial Distribution

空间多目标空域分布是指目标群在飞行过程中的空间相对位置关系和运动状态,是评估武器系统性能的重要参数。测控系统对该参数的获取越来越重视,但是对空域分布的描述还没有形成统一的认识。从目标探测和目标识别角度提出了一种解决方案,按照多目标在空间散布的形态把空域分布划分为直线分布、平面分布和立体分布3种类型,定义了各种分布类型的描述参数,并给出了各类参数的解算策略和方法步骤。用10个目标构成不同分布形态的目标群,仿真测控系统对其跟踪解算过程,解算结果与空域分布设计一致,验证了分析和解算方法的正确性,该方法可以在试验任务中推广应用。

Used to describe the pattern of relative position and the motion of multi-targets in flight, spatial distribu tion is an important parameter for evaluation of the performance of a weapon system. In spite of increasing attention of spacecraft TT＆C （Telemetry, Tracking and Command） in spatial distribution, consensus has not yet been reached on description of the parameter. A definition of spatial distribution is given in this paper for multi targets from the perspective of target detection and target recognition. Three patterns （straight line, plane, three-dimen- sional） are used to describe spatial distribution of multi-targets with series of arguments, and solving strategies and procedures are given with calculation formulas for each argument. Simulation of the solution process by a TT＆C system is performed with 10 targets in each spatial distribution, and the results are in agreement with designed spa tial distributions. It is verified that the analysis and calculation methods given in this paper are correct and can be ap plied in test missions.
