阵列光幕测试系统目标识别方法

Testing System of Target Recognition Method of Array Screen

为了解决现有阵列光幕测试系统无法对多个连续目标信号进行判断和识别和单元探测光幕易受外界干扰的难题,提出了利用相似性系数法对单元探测光幕中光电探测器阵列输出的干扰信号进行剔除,再根据D-S证据理论对阵列光幕探测系统输出信号的目标类型进行判断和识别的方法。研究目标穿过阵列光幕测试系统输出信号的特点,给出了以阵列光幕测试系统4个单元探测光幕为证据体下的输出信号目标类型的信度函数分配,再经过融合处理得到目标识别的结果。

In order to solve the problem that the existing array screen test system cannot judge and recognize multiple continuous target signals and the unit detection screen is susceptible to external interference,the principle of using the method of similarity coefficient is proposed.To distinguish the real target signal and interference signal of each unit detection screen output,based on the D-S evidence theory,a method to identify the real target signals and eliminate the false targets in the test system of multi photoelectric detection sensors is established.The characteristics of the output target signal which pass through the array screen test system are studied,and the distribution of the reliability function of the output signal target type under the evidence body of four unit detection screens in the array screen test system is given,and then the target recognition result is obtained through fusion processing.So this paper can achieve the goal of eliminating the false targets and signal recognition.
