Radar Signal Real-time Sorting Of Technology

With the development of modern radar technique and its widespread application, the modern electromagnetic environment with the characteristics of dense,overlapping,complicated and mutable brings great threaten to reconnaissance equipment, and high expectation to signal processing of radar reconnaissance equipment. How to implement effective reconnaissance, signal sorting and jamming becomes an urgent problem in electronic countermeasures.The radar signal sorting is the key component of electronic reconnaissance equipment and the foundation and precondition of radar characteristics abstraction,identification and threaten evaluation. The main content of the paper is radar signal sorting system design and realization. The dilution and clustering of mass overlapping parameter flow and de-overlapping ability improvement of real-time pulse have been implemented by using CAM technique in the article. The signal sorting algorithm based on PRI is discussed in detail and the real time and accuracy ability is increased by the algorithm optimization. The high speed DSP parallel processing and high speed large-scale FPGA hardware platform is used to realize the signal pre-sorting of key target according to the known radar signal characteristics. As a result, the signal sorting speed is greatly increased and the real-time radar signal sorting is implemented. The radar signal sorting equipment is composed of parameter measuring circuit, signal pre-sorting and signal chief sorting circuit.
