The Blind Speed Side Lobes (BSSL) may increase the false alarm probability and deteriorate the detection performance of the long time coherent integration method, namely, the Radon-Fourier Transform (RFT). A novel BSSL suppression method based on the design of radar Pulse Recurrence Interval (PRI) is proposed. First, detailed PRI design method is given based on the BSSL locations and velocity resolutions. Then, by jointly processing the RFT outputs of two adjacent Coherent Processing Inlervals (CPIs), the BSSL suppression can be realized without deteriorating the integration performance of the RFT. Finally, detailed numerical experiments are provided to demonstrate the effectiveness of the proposed method.
