The Design And Implement Of Seeker Target Simulation System

With the development of scientific and technological level,seeker researching has entered a new stage of development.Target simulation technology as a production of seeker development,play an important role.In the system designing stage,the target simulation can be more accurately assess the seeker designing performance.In the prototype stage,the target simulation can debug the parts and the system,shortenly the time of desiging.In the service stage,the target simulation can be a means of seeker testing evaluation,it also provides an environment for users to master seeker usage.Based on the above functions,the target simulation increasing activitly,it will become an important branch of seeker research.This paper states a seeker target simulation system.mainly focused on the hardware realization,the software designing,the prototype development and the system testing,etc.The main research content six parts.The introduction part firstly elaborates the background and significance of this topic research.Outlined the main researching contents and the situation at home and abroad.Summarized the main contribution and innovation,finally gives the researching framework of this paper.The chapter two presented the designing ofthe target simulation systemand the details of the technical indicators.To determine the comprehensive assessment and system designing ideas,such as the composition and structure.The module functions are described,they are the guiding chapters.The chapter three puts forward the injection target simulator in full coherent and the working conditions.Describes the target simulator for host,and front end design scheme of the target simulator,multiplier,mixer,filter and amplifier module design.At the same time,the angular motion simulator and hardware scheme has also done a narrative.The chapter four described the target simulator software designing.Target simulator software is divided into three parts: the upper control software,software interface and logical control software.Respectively on PC platform upper control,software was compiled with C # language,on DSP platform is developed in C language.Then implemented on FPGA platform using Verilog HDL language.This chapter presents three software parts of implementation code.In the third part,the softw achieving the target simulator software functions.The chapter five finished the target simulation system test verification work.Using the known parameters of seeker equipment,fully test have been carried out to verify the target simulation system,this paper gives the seeker is stable,searching for some typical test data,tracing,etc.The goals of the test results show the developing simulation system.Finally,this system successfully applied to a model seeker in development work.The chapter six summarized and prospect,points out the further perfect target simulation system needs to carry out the work.
