中文摘要:
      针对主动声呐作用距离指标试验评定考核,阐述主动声呐作用距离指标定义,明确主动声呐作用距离是主动声呐满足规定检测概率的作用距离,提出一种主动声呐作用距离指标试验评定方法,即根据主动声呐以重复的单次发射和检测方式工作的特点,首先以滑动窗采样周期的形式检验声呐检测目标的概率,其次规定3次试验航路至少2次达标的标准,以验证基于发现概率的声呐作用距离,进而验证声呐技术规范规定的检测概率,使得海上试验结论可信度高。该评定方法可作为主动声呐作用距离指标评定考核的一种依据,为声呐装备试验、训练提供参考。
英文摘要:
      Aiming at the test evaluation of active sonar range index, the definition of active sonar range index needs to be explained. It is clear that the active sonar range is defined as the range that the active sonar meets the prescribed detection probability, and then a test evaluation method for active sonar range index is proposed. Due to active sonar operating in the repeated single emission and detection mode, the detection probability of sonar finding target is tested with the sampling period in a sliding window, and then, the standard of testing active sonar range is stipulated in the way that the active sonar meets a certain detection probability at least 2 times in 3 test routes. The detection probability stipulated in the sonar technical specifications is further verified, which increases the credibility of sea-trial conclusion and can be used as a basis for the evaluation of active sonar range index and a reference for sonar equipment testing and training.
