Transmit pattern synthesis for MIMO radar

This correspondence provides a new method for the optimal design of transmit pattern synthesis of MIMO radar using independent mainlobe and sidelobe constraints. Given fixed pattern mainlobe errors, we apply quadratic inequality constraint to sidelobe level. In order to enable the resulting covariance matrix to fulfill the practical uniform elemental power constraint, a basis set is constructed which converts the solution of the covariance matrix into the optimization of the coefficients of the basis matrices set. It can not only reduce the computing complexity of the original optimal model, but also can be solved effectively by the convex optimization. In addition, the scale factor of the desired beam is set as the unite variable so as to reduce the matching error of the MIMO radar pattern further. Simulations are presented to illustrate the superior performance of the transmit pattern via the proposed method.
