海上目标无源态势感知技术试验研究
A Study on Passive Situation Awareness System for Maritime Targets
摘要
Abstract
Accurate situational awareness of maritime targets in 24/7 is crucial for safeguarding national maritime rights and ensu-ring maritime safety.In response to the limitations of existing passive detection technologies such as wireless detection and photoe-lectric detection in detecting target types and multi-target detection capabilities,as well as the anti-interference and concealment capabilities of active radar,experimental research on passive perception technology for sea targets based on pulse radar signals was conducted,targeting various ships on the sea surface.The basic principle of passive situation perception system for targets detec-tion was provided.The measurement of direct wave pulse signal parameters,analysis of antenna scanning characteristics and data pre-processing,pulse accumulation and moving target indication processing,constant false-alarm rate detection and display correc-tion were completed based on field measurement data.The trial results were verified and analyzed using ship automatic identifica-tion system information,which verified the feasibility and effectiveness of maritime targets detection by passive situation perception technology based on non-cooperative pulse radar signals.关键词
