Title: The research on Doppler ambiguity for dual pulse repetition frequencies radar
Abstract: Based on the one-to-one relationship found in the fact that the velocity in a two-dimensional space is projected onto a one-dimensional space during resolving velocity ambiguity, mathematical deduction of the number of pulse repetition intervals required in each coherent process interval to satisfy quantitative requirements is presented to resolve velocity ambiguity in dual pulse repetition frequencies radar systems. Simulation results validate the accuracy of our deduction. By constructing different sampling intervals in each one-dimensional space, a new improved fast approach is proposed to effectively resolve Doppler ambiguity based on clustering algorithm and the fast Fourier transform (FFT) when the number of pulse repetition intervals is not enough to satisfy quantitative requirements in dual pulse repetition frequencies radars. Numerical studies have demonstrated the effectiveness of the proposed method.
