Abstract:

A method for the orthogonal serial phase code waveform design of multiple input multipleoutput radar based on sequential cone programming is proposed, which minimizes the autocorrelation peak sidelobe level (APSL) and cross correlation peak level (CCPL) of transmit signal as its objective function. Taylor approximation is adopted to transform the original problem which is non-convex into a series second order cone programming problems via sequential cone programming framework in each iterative point. Moreover, in order to improve the optimal results, the threshold of phase increment is constrained as a linear function. Finally, simulations show that the orthogonal waveform performance is better than the reference method when the number of the transmit array and the code is same. At the same time, the APSL and CCPL can be accurately controlled respectively by using the proposed method, which is very flexible for the orthogonal waveform design.
