An Algorithm of Recognization the PAR’s Working States Based on Intrapulse Analysis

Sorting phased array radars’ pulse train from a complicated electromagnetic environment is a difficult and important problem for electronic support measures (ESM). There have been so many papers to sorting the PAR’s pulse trains. But, how to use the sorted pulse trains to distinguish the PAR’s working states, has been a problem to be solved. This paper using have been sorted phased array radar’s pulse trains, proposes an intrapulse analysis method to distinguish the PAR’s working states. By applying the method in the experiment, we can get a result of distinguished the working states of the PAR. From the result, we can get the transformation of the PAR’s working states.
