Anti-sorting Signal Design Applied to Radio Frequency Stealth Radar based on Pulse Repetition Interval Slide

With the extensive application of wireless equipment, electronic warfare is becoming the key to winning modern wars. Improving the anti-reconnaissance performance of radar is an important means to enhance radar electronic countermeasures. And anti-sorting signal design can fundamentally enhance the anti-reconnaissance capability of radar. Aiming at the sequence difference histogram algorithm widely used in signal reconnaissance, the anti-sorting signal is designed from the point of destroying the estimation value of signal pulse repetition period by sorting algorithm. In this paper, the working steps of the sequential difference histogram sorting algorithm are firstly sorted out and the key steps of the algorithm for signal sorting are analyzed. Then the signal design scheme is proposed. Finally, the simulation results show that the designed signal can effectively counter the sorting algorithm.
