    As the typical signal of Aegis radar, the intra-pulse multi-carrier frequency signal has awesome advantages of anti-interception and anti-jamming. However, its signal processing method is unclear. Taking the intra-pulse four-carrier frequency signal as an example, its signal characteristics and processing methods are studied. Based on the principle of optimal detection probability, the possible processing methods are proposed, and the processing framework and process are given. Especially for the case of aiming interference, the interference detection algorithm is employed to eliminate the interfered sub pulses. The detection performance of the two processing methods in different scenarios is compared through signal level simulation. The conclusion provides a reference for the processing and application of intra-pulse multi-carrier frequency signal.
