[Abstract]:With the continuous development of radar technology, the signal environment in the battlefield is influenced by the intersection of various parameters and different radar radiation signals, so the radar reconnaissance equipment located in the battlefield has higher performance requirements.In the development of new radar reconnaissance equipment, in order to accurately test the location performance of reconnaissance equipment, it is necessary to provide a real battlefield signal group environment as the experimental basis.However, it is impractical to reconstruct the signal environment by using real emitter equipment, which is influenced by many factors, such as external climate, experimental site and experimental funds.Therefore, it is of great significance and value to develop a simulation software that can deal with this problem to restore the real battlefield signal group environment.Based on the research of dynamic simulation of complex signal environment, this paper designs and implements the "dynamic simulation software of complex signal environment", which provides a powerful external signal environment support for the development of radar reconnaissance equipment.The main contents of this paper are as follows: first, by comparing the existing radar signal environment simulation technology, analyzing their advantages and disadvantages, selecting the appropriate theoretical and technical support for this project, then according to the needs of the project analysis,The whole design scheme of the software, the realization scheme of data simulation and the scheme of generating radar pulse signal description word are put forward. Secondly, the common radar pulse signal is analyzed, and the mathematical model of radar pulse signal is established.According to the location of the radar emitter and the moving track of the receiver, the communication model .3between the radar and the receiver in three-dimensional space is established. Then, according to the software design scheme and the mathematical model,Through the test and verification of the test platform, the dynamic simulation software of complex signal environment in this project can guarantee the data accuracy and integrity under the condition that the precision of time interval is 0.1 s.Twenty radar pulse signals are simulated accurately under the superposition of the signal environment data and the pulse description words to record the radar pulse information.The corresponding pulse description word is compared and verified, and the data meet the requirements of each item.
