| With the deterioration of space spectrum environment,the short-wave reconnaissance control system is prone to find spurious response and it becomes more and more difficult to receive signals.At the same time,due to the small step size of short-wave signal,a single short-wave receiver cannot perform the rapid scanning of full-band short-wave signal,which makes the detection and control of short-wave signal more and more difficult.In contrast,the short-wave wideband reconnaissance control system USES multiple short-wave wideband detection receivers to form a network,and carries out data fusion analysis through the server-side software platform,and finally USES the client-side software platform to conduct full-band signal scanning and control.It is of great practical significance to solve the difficulties in the field of short-wave signal detection and control with systematic thinking.Firstly,based on the specific user requirments,this paper describes the relevant concepts and architecture of HF broadband detection and control system in detail,and determines the system design scheme.Through the software outline design of the system,the software architecture,organization structure,design idea and flow are difined.The system is mainly composed of five modules: network communication,equipment management,reconnaissance guard,multi-channel guard,channel list and voice repetition.Secondly,this paper designs and implements the system,including UI(User Interface)design,software interface design,process design,device management module design,log module design,reconnaissance control module design,channel list module design,voice repeat module design,data storage module design and network communication module design.In the process of software design,each module is designed through multiple levels: activity diagram,use case diagram,sequence diagram,code realization logic description,and UI interface and so on.Finally,in the chapter of software testing,a distributed networking test environment composed of several HF broadband reconnaissance receivers is built to test the main functions of the system.The test results show that each function of the system runs normally and has a good the real-time performance,which meets the design expectations. |
