Abstract

Abstract

A novel low sidelobe method is proposed through the improvement of the classical method of MIMO radar transmit waveform design. Firstly, two parameters, involving the lower boundary and the upper boundary of the mainlobe of the transmitted waveform, are introduced. While the value of the lower boundary is given. Secondly, a semidefinite programing optimization problem is established, whose objective function is minimization of peak-sidelobe or integrated-sideloble. The transmit waveform covariance is semi-positive and the signal power of each array element is fixed. Further, the restriction on the mainlobe fluctuation is added to the constraint of the optimization problem. Whats more, if the upper boundary is changed, the mainlobe fluctuation and sidelobe will be changed simultaneously. Finally, only once convex optimization algorithm is used to obtain the global optimal solution. The simulation results show that the proposed method has the advantages that the sidelobe is lower and can be contolled
- MIMO radar,
- Transmit waveform design,
