| Marine environmental monitoring is of great significance in China’s economic development and national defense construction.The research content is based on the background of "Research on wave inversion technology of ship borne X-band radar",relying on the research and development of wave monitoring equipment of marine public welfare scientific research project,aiming at the research and development of composite video navigation radar signal adapter of wave monitoring equipment subsystem.The research content of this paper is based on the development process of the signal adapter of the composite video navigation radar,which includes the analysis of the composite video signal,the design and implementation of the software and the software testing.The terminal of anshutz navigation radar system outputs one channel of composite video signal,which is composed of many parts and different from the four channels of traditional radar signal.The information inversion of the wave monitoring equipment cannot be separated from the radar information data.The radar signal adapter is responsible for the collection of the data.Because the technical confidentiality ship has no complete technical data about the anshutz navigation radar,in order to study the meaning of the signal to complete the collection of data,it is necessary to study the interface between the radar signal adapter and the anshutz navigation radar.In this paper,the characteristics of the signal source are analyzed and the radar signal acquisition scheme is determined.Then,a self-made auxiliary analysis tool is used to complete the signal protocol analysis of the composite video signal in SP,M1 and M2 modes through multiple statistical and comparative experiments,and the information including video signal,bow,azimuth and distance is determined.The radar image drawn according to the protocol is consistent with the true value,and the composite video signal is verified The accuracy of video signal protocol.Wave information inversion is based on radar image data.In this paper,radar signal adapter software is designed to complete the composite video signal acquisition of anshutz navigation radar.Through the analysis of software function,interface and File protocol requirements,the function of radar signal adapter in ocean wave monitoring system and the platform and environment of software application are determined;the function of each module and the relationship between modules are established through UML modeling,UI design and other outline design of software;the realization is realized through the detailed design of software architecture,process and function module The overall development of the signal adapter software for the composite video navigation radar is presented.The function and performance of the signal adapter software of the composite video navigation radar are measured by software test.After introducing the commonly used software testing methods in the Internet industry,this paper determines that software testing can be implemented in two ways: laboratory simulation testing and outfield joint debugging testing.Among them,the laboratory simulation test completed the unit test,integration test,system test and delivery test,which verified that the function and performance of the software meet the user’s needs;while the outfield joint debugging test further verified the overall working performance of the system in the real experimental environment,and confirmed the reliability of the radar signal adapter software,and assisted in explaining the composite video signal protocol accuracy. |
