【摘要】：針對戰(zhàn)場目標分群中存在的類數(shù)未知和閾值選取欠缺有效方法的問題,提出一種基于改進空間劃分的目標分群算法。首先,通過敵我及作戰(zhàn)單位屬性劃分,約減分群目標數(shù)規(guī)模,降低計算量;其次,通過對空間距離劃分進行改進,能夠動態(tài)地優(yōu)選閾值,有效解決類數(shù)未知的分群問題。通過引入劃分獨立性和逆χ~2分布概率區(qū)間約束,消除計算冗余并提取出候選閾值,在此基礎上選取最大的候選閾值作為最終分群閾值,可以有效濾除過程噪聲與觀測噪聲干擾,提高分群準確率。仿真結(jié)果表明,該算法對戰(zhàn)場環(huán)境下的多目標編隊分群具有良好的有效性、穩(wěn)健性和實時性。
[Abstract]:In order to solve the problem of unknown class number and lack of effective method of threshold selection in battlefield target clustering, a new algorithm based on improved space partition for target clustering is proposed. First, by dividing the attributes of the enemy and the other and the operational units, the size of the number of targets in the cluster is reduced, and the computation is reduced. Secondly, by improving the space distance division, the threshold can be dynamically selected and the clustering problem with unknown number of classes can be effectively solved. By introducing partition independence and inverse 蠂 ~ 2 distribution probability interval constraints, the computational redundancy is eliminated and candidate thresholds are extracted. On this basis, the largest candidate threshold is selected as the final clustering threshold, and the process noise and observation noise interference can be effectively filtered. Improve the accuracy of clustering. Simulation results show that the algorithm is effective, robust and real-time for multi-target formation clustering in battlefield environment.
