为了能有效利用敌我识别器提供的信息对雷达所发现的目标进行敌我属性识别,研究了直角坐标系下雷达与IFF正常配置(IFF系统的应答信号的所在方位与雷达目标回波方位相同)时的相关问题。基于卡方分布检验理论和n/m逻辑准则,提出了直角坐... 为了能有效利用敌我识别器提供的信息对雷达所发现的目标进行敌我属性识别,研究了直角坐标系下雷达与IFF正常配置(IFF系统的应答信号的所在方位与雷达目标回波方位相同)时的相关问题。基于卡方分布检验理论和n/m逻辑准则,提出了直角坐标系下雷达与IFF正常配置时的相关算法。首先,基于卡方分布检验的思想,对于两坐标、三坐标雷达与IFF相关分别构造了平面、空间相关判别函数,给出了决策规则及决策门限的计算方法,讨论了多义性问题的处理;然后,为了提高正确相关概率和减小误相关概率,使用n/m逻辑进行相关判决;最后,进行了计算机仿真。仿真结果表明,该算法在将误相关概率控制在较低水平的同时,可以获得较高的正确相关概率。 展开更多

Private financing is a supplementary of financial services and capital market allocation of resources, and it is also an important financing channel for SMEs and an important factor which has great impact on economic and financial operations. However, with the growing scale of private financing, there are large potential risks which affect the normal operation of private financing, and even affect the long-term development of financial markets. This paper analyzes the current situation of private financing and risks existing in current private financing, and propose some ways to avoid the risk of private financing, to provide a theoretical basis for future research on private financing risks. 展开更多
