Recognizing the operation modes of airborne fire control radar quickly and accurately,especially in the high threat mod,is the important part of airborne electronic countermeasures.For the restricted application conditions of existing methods,a new method using amplitude rearrangement is proposed in this paper after a large amount of analysis of each mode.This method makes full use of the characteristics of amplitude distribution to identify tracking signals.First,all the signals are rearranged by the size of signal’s amplitude,and then the first-order difference of the rearranged amplitude iscalculated.Finally,the track and search mode and single target tracking mode are recognized effectively according to the special notch character of the rearranged amplitude.Simulation results prove the good real-time and accuracy rate performance of the proposed method.More importantly,the new method is not sensitive to the pulse deletion and interference.Owing to the above advantages,the proposed method has a good potential in the practical engineering application.

Key words: airborne fire control radar, operation modes recognition, amplitude
