摘要
针对相位编码信号的高旁瓣问题,提出一种基于二阶锥规化的峰值旁瓣抑制滤波器设计方法。将最大增益处理损失约束下的最小峰值旁瓣滤波器设计转化为二阶锥规化问题,采用内点法进行高效求解。与已有方法相比,所提方法可以兼顾峰值旁瓣、处理增益损失和滤波器长度三方面的指标,具有设计灵活、精度高和收敛性好的优点。最后仿真和实测数据结果验证了方法的有效性。
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 meth od 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.
