摘　　要：为了提高鱼雷引信的调试质量,根据鱼雷引信调试对电磁环境均匀性的要求,提出了鱼雷引信电磁环境的均匀性判定方法。基于鱼雷引信接收装置的结构特点,采用两个对称的9元传感器测量阵列对电磁环境进行测量,利用移动最小二乘法对测量值进行拟合预处理,根据鱼雷引信的磁灵敏度进行不均匀性概率的计算,并结合鱼雷引信的虚警概率及其接收机的幅频响应,给出了鱼雷引信电磁环境的均匀性判定标准。通过实测数据的计算,验证了所提出方法的正确性与合理性。Due to the debug requirement of torpedo fuze to electromagnetic environment uniformity,a judgment method of electromagnetic environment uniformity to torpedo fuze is put forward to improve the debug quality of torpedo fuze.Based on the structure characteristic of torpedo fuze receiving equipment,electromagnetic environment is measured by two symmetrical 9-sensors measuring arrays and the measured data is pre-processed by moving least-squares method（MLS）.Then,nonuniformity probability is computed according to magnetic sensitivity of torpedo fuze.The judgment criterion of electromagnetic environment uniformity to torpedo fuze is given by using false alarm rate of torpedo fuze and amplitude frequency response of its receiver.The computation result of measured data validates the correctness and rationality of the proposed method.
