Aiming at the process of radiation source recognition needs along time and high threat level radiation source can not be found in time in compex electromagnetic circumstance,the fast filtration and recognition of key radiation source targets based on pulse sample figure are mainly researched in this paper and a algorithm based on pulse sample figure level of TOA difference is also proposed. The process uses the full pulse which has been simply disposed matching the pulse sample figure of the key radiation source and then outputs the key radiation source target recognition results after ignoring the overlap matching. The filtration and recognition can complete synchronously. The computational complexity is small and the speed of filtration and recognition is fast. Simulation results show that this method can recognize the key radiation source fast and efectively,and also has high engineering application value.
