Abstract
Complete complementary sequence (CCS) has ideal correlation performance along the zero Doppler axis. However, its correlation property is extremely sensitive to the Doppler shift. In this letter, by employing a sequential quadratic programming (SQP) optimization method, a novel design of the Doppler resilient CCS is presented for multiple-input multiple-output (MIMO) radar. Compared to the existing methods, this design can reduce the range sidelobes associated with a matrix-valued ambiguity function without restrictions on the waveform number, the pulse number and the waveform length. In addition, the superior orthogonality of CCS can also be achieved. Several numerical examples are provided to demonstrate the effectiveness of this design.
