| 摘 要： | 为确保反鱼雷鱼雷（ATT）与来袭鱼雷交会过程中激光近炸引信能够探测到目标，推导能够满足要求的扫描频率和脉冲频率计算公式。研究激光近炸引信工作原理，得到激光近炸引信恰能探测到目标所需的激光束最低扫描频率和脉冲激光最低脉冲频率的临界条件。采用三种坐标系描述ATT 与目标间的交会关系，基于交会关系和临界条件，建立最低扫描频率和最低脉冲频率计算模型，获得最低扫描频率和最低脉冲频率的变化规律，并通过模拟试验验证所建理论模型的正确性，试验结果与理论计算结果吻合。计算拦截不同典型目标鱼雷时所需最低扫描频率和最低脉冲频率取值。所得计算模型和结果可为激光近炸引信应用中扫描频率和脉冲频率设计提供理论依据。

| Abstract: | To ensure laser proximity fuze of anti-torpedo torpedo (ATT) detecting the torpedo target in rendezvous process, the minimum scanning frequency and the minimum pulse frequency that can satisfy requirement was calculated. The working principle of laser proximity fuze was studied, and the critical condition of the minimum scanning frequency and pulse frequency that make the fuze just detect the target were obtained. The rendezvous relations between ATT and target were described by three kinds of coordinate system, the computation models for the minimum scanning frequency and pulse frequency were built, and the changing rules of the minimum scanning frequency and pulse frequency were got. Through simulation test to prove the correctness of the built computation models, the test results tally was in line with the theoretical results. The minimum scanning frequency and pulse frequency that is necessary to intercept different typical torpedoes were calculated. Thus, this work can provide a theoretical basis for designing the scanning frequency and pulse frequency of laser proximity fuze. |
