Research On Technology Of Real-time Simulation Of Complex Radar Signal Environment

With the rapid development of information technology,radars are more and more widely applied in all kinds of electronic equipment,which are not only with large quantity and big density,but also with the continuous development of all kinds of new systems of radars,the radar signal waveform became more and more complex.In order to test the performance of variety of electronic equipment in Complex Rader Signal Environment.Research on technology of Real-Time Simulation of Complex Rader Signal Environment is of great significance.In this paper,Firstly,the Complex Rader Signal Environment and its characteristics and PDW model of Complex Rader are being recommended.This paper proposed a characterization method of complexity of simulation of Complex Rader Signal Environment;Then,I designed for two methods of Real-Time Simulation of Complex Rader Signal Environment.They were Real-Time Simulation of Signal based on DDS and Up-Conversion and Real-Time Simulation of Signal based on Synthesis Filter Bank.Given out the overall design ideas and working principle of each scheme and the implementation of each function modules.Then,I designed for scheduling methods of Real-Time Simulation of Complex Rader Signal Environment under each scheme respectively.Given out two scheduling methods and scheduling sequence processes of Real-Time Simulation of Complex Rader Signal Environment under each scheme algorithm,and also given out the scheduling principles under different simulation requirements.Finally,I carried on the simulation verification and test evaluation of the output of scheduling.
