Abstract :
A novel recognizer that automatically reports the PRI (Pulse Repetition Interval) modulation type of a radar pulse signal is developed. The proposed method utilizes the features based on the properties of PRI sequence for each PRI modulation type both in time and frequency domain. These features are defined as zeros-crossing density, harmonic amplitude ration and sign properties of difference of the PRI sequence, which can be easily extracted from PRI sequences with small samples size. In addition, the proposed method also can be used to estimate the PRI modulation period for the periodic PRI modulation type signals. Simulation results show that the proposed approach is robust in the presence of measurement noises, missing and spurious pulses.
