Research on the Sequential Difference Histogram Failure Principle Applied to the Signal Design of Radio Frequency Stealth Radar

As electronic warfare becomes the core of modern warfare, radio frequency (RF) stealth radar is becoming focus warfare. The anti-sorting strategy RF a new effective method anti-enemy reconnaissance system. Hence, research on failure mechanism sorting algorithms has become cornerstone technology. In this paper, algorithm studied because SDIF widely used in engineering practice throughout whole workflow sequential difference histogram (SDIF) algorithm, from estimation pulse repetition interval (PRI) destroyed by and analysis to staggered signal. Firstly, working steps are considered. Key signal analyzed, principle proposed. It pointed out that if PRI center value two groups radars within tolerance range when values not same order magnitude, more than 10 times, variation less 30% value, error for at least 25%. fails sort signals. At time, signal, sub-PRI design formula proposed, satisfying can make invalid. Finally, correctness further verified derivation, simulation experiment. provides theoretical support foundation makes up shortcomings random improves efficiency
