Abstract
Traditional radar signal sorting methods have expensive cost on computation in pulse repetition frequency( PRF) detection and initial arrival time( IAT) estimation respectively. To solve this problem,a novel sorting method based on spectrum estimation is proposed. The method cuts down the operational times for IAT estimation by removing the harmonics,and determines the IAT while detecting the periodicity of a pulse train,thus avoiding the conventional traverse of sequence and saving the computational resource. Simulation results demonstrate its feasibility and efficiency.关键词
