Abstract:

For the problem of the highsidelobe from the match filtering using the codedsignals, a method of peak sidelobe suppression filter design based on secondorder cone programming is proposed. The design of minimum peak sidelobe filter, considering the maximum loss in process gain, is converted to a secondorder cone programming problem, which can be solved with great efficiency by interiorpoint method. The proposed method provides the optimal tradeoff among the peak sidelobe level, the loss in process gain and the filter orders, which has many advantages over those available, such as flexible design, high accuracy and good convergence. The validity of method is confirmed by the result of the simulated data and the measured data.
