Design Principle of Staggered Shielding and Anti-sorting RF Stealth Signal Based on Staggered Signal Combination
Radio frequency(RF)stealth radar is a research hotspot in radar field at present.Signal d-esign is the key link to achieve RF stealth.Aiming at the main sorting algorithm-sequence difference histogram sorting algorithm widely used in real-time broadband electronic reconnaissance equipment such as radar warning receivers.It is pointed out that in the sorting process of staggered signals,it is difficult to analyze the staggered signal if the SDIF algorithm cannot select multiple radar signal which the multiple pulse repetition interval values equal to the skeleton period T.Therefore,a design method of RF alternating shielding anti-sorting signal based on the combination design of staggered signals is proposed.The combination design is carried out with the three adjacent sub-staggered signals PRI as a group,and the designed staggered signals will alternate cover in different steps of the sorting algorithm,resulting in the increase of the output signals of the sorting algorithm,or even the output of completely wrong results,and then the radar signal cannot be effectively sorted.The simulation and experiment show that the staggered signal designed according to the signal design principle can effectively counter the sorting algorithm,a theoretical basis for anti-PRI sorting signal design is established.
