Aimed at radar emitter recognition in complex electromagnetic environment. This paper started with character of signal, made use of spectrum theory to take out the cyclostationarity frequency of radar signal, extracted the characters in cyclostationarity dimension, realized separation and recognition of radar signal with the characteristic and the degree of cyclostationarity(DCS) separation criterion based on second order cyclic statistics. This method had an advantage of keeping phase information, fewer calculation and strong anti-noise capacity. The method was verified the effectiveness to separate and recognize radar signal by means of formula derivation and simulation.
