摘要:
为了探讨鱼雷主动隐蔽探测技术的可行性及实现途径, 建立了由自导接收机模型、侦察接收机模型以及水声信道模型构成的低截获自导系统模型。在此基础上, 对鱼雷主动隐蔽探测的性能进行了理论分析和仿真评估, 给出了鱼雷主动隐蔽探测距离的预报。最后, 从大时间带宽积信号的生成和处理两方面进行了鱼雷主动隐蔽探测的可行性分析, 提出了采用主动连续波自导来实现鱼雷主动隐蔽探测的技术途径, 为鱼雷主动隐蔽探测的工程实现提供依据。
Abstract: To discuss the feasibility and realization of torpedo active concealed detection technology, a model of low probability of intercept(LPI) homing system are established, including a model of homing receiver, a model of reconnaissance receiver and a model of underwater acoustic channel. Then theoretical analysis and simulation evaluation on the performance of torpedo active concealed detection are performed, and forecasting of torpedo active concealed detection range is given. In addition, feasibility analysis of torpedo active concealed detection is carried out from the aspects of the generation and process of large time-bandwidth product signal, and technical route for realizing the torpedo active concealed detection through active continuous wave homing is proposed, which may provide an approach for engineering implementation of the torpedo active concealed detection -
