Abstract
Most ready-made signal sorting algorithms does not perform well when the pulse repetition frequency (PRF) jitter and the PRF stagger signals impinging on the radar simultaneously. In view of this, an effective and fast signal sorting method based on dual-PRI Transform is proposed. In this correspondence, we fully exploit the differences between the jittered and the staggered signals to segment the mixed signals. The proposed algorithm consecutively implements two pulse repetition interval (PRI) transforms, followed by the first order sequential difference (SDIF) histogram, to analyze the signals. The experimental results verify the proposed method is simple and easy to implement, and the accuracy is high.
