Optimization design for robust waveform of MIMO radar under condition of uncertain target prior knowledge
摘要
Abstract
The robust waveform optimization is considered to improve the parameter estimation accuracy of multiple-input and multiple-output (MIMO) radar under worst condition. On the basis of the min-max approach,the initial parameter error model is contained in the waveform optimization explicitly,and the robust waveform design is obtained on the basis of Cramér-Rao bound(CRB). To solve the obtained complicated and nonlinear optimization problem,it is converted into the semi-definite programming(SDP)problem by means of Hadamard′s inequality to get the efficient solution. The simulation results show that, in comparison with the uncorrelated transmitted waveform and non-robust method,the method can improve the parameter estima-tion performance under worst condition.关键词
