摘要：

This paper proposes an efficient method for maneuvering targets with arbitrary migrations. This method first employs bisection range frequency conjugate to blindly align the envelopes. Then, the recursively parametric scaled correlation transform is applied to obtain the estimates. The proposed method is free of searching, thus significantly improves the computational efficiency on the premise of retaining the performance. Both simulated and real data verify the effectiveness of the proposed method.
