摘要
通过对雷达/红外成像双模导引头探测目标工作机理的研究,根据贝叶斯假设检验,分别建立了分布式检测(并行结构)最优融合规则、"与"规则和"或"规则条件下的目标检测概率模型,经过仿真验算,验证了三种规则下信噪比与检测概率之间的关系,并以全系统运行风险为指标,对三种规则条件下的全系统风险作了比较,研究结果对提升双模导引头探测能力具有实际参考价值。
According to working mechanism of missile's dual-model seeker detecting target and Bayes hypothesis testing,modeling detection probability under the optimal fusion rule,"and"rule and"or"rule of distributed detecting target( parallel structure) was conducted,the relationship between S/N and detection probability under the three rules was proved by simulation. At last,system operational risk was taken as index,risk comparison under the three rules was made. The result has practical reference value in improving missile seeker detectivity.
