雷达测角存在误差情况下,多雷达数据融合系统中,由于错误关联生成了幻影。伴随测角雷达、干扰目标数量增加,幻影数呈级数增长。针对上述问题,利用雷达间关联张角,确定雷达组合间的候选观测集,并在此基础上利用模糊聚类法建立多雷达组合定位中的幻影剔除算法,通过验证算例可以看出该算法能够很好地解决上述问题。
Several factors cause the number of simulacrums increase rapidly, leading to rapid increase amount of time required for signal processing. We now offer an effective method that we believe can reduce the time required. Essentially we do two things: (1) the utilization of angles,each of which angle between two lines respectively from two radars directed toward target; (2) the application of in the much is an fuzzy clustering method. In a numerical example, we give a seven-step procedure of our method for 3-radar orientation location of target.it does succeed in eliminating simulacrums and obtaining the orientation location of the real target with much reduced time of signal processing.
