[Abstract]:With the rapid development of radar technology, the radar system is developing towards diversification, complexity and integration. The electromagnetic environment of electronic countermeasure is becoming more and more complex. How to realize the high performance sorting of radar signal in complex signal environment becomes a key problem in radar countermeasure. This paper studies radar of radar reconnaissance system. The influence of the signal sorting method and the separation method on the performance of the radio frequency target is mainly analyzed. The radar signal parameters and its variation patterns are introduced in detail in this paper, and the influence of the characteristics of the radio frequency target and the variation of the radio frequency target on the separation performance are analyzed in detail. This paper studies the flow of radar signal sorting, combs the main methods of radar signal sorting from two aspects of pre-sorting and main sorting, and defines the performance index of radar signal sorting. According to the principle of parameter distribution and separation, the mathematical model of radar signal sorting is established, and the influence of each characteristic change of radio frequency target on each link is analyzed one by one by theoretical derivation. Finally, the simulation software of radar signal sorting is compiled, and the research results in this paper are simulated with the software. The results show that, The conclusion in this paper is reasonable and provides a basis for improving the performance of radar signal sorting.
