摘　　要：针对假定的杂波区,通过规划的频谱确定滤波器频率中心,以最小化杂波输出功率为目标建立凸优化模型,利用CVX求解满足约束条件的滤波器组系数,根据优化设计的滤波器组最大频率响应检验杂波抑制效果,不满足设计要求时则改变滤波器组的设计参数,迭代设计以实现对杂波的目标抑制比。For the assumed clutter area,the frequency center of the filter is confirmed through the planned frequency spectrum,and the convex optimization model is built to minimize the output power of the clutter.The coefficient of the filter bank that satisfies the constraint conditions is obtained via the CVX,and the clutter suppression effect is tested based on the maximum frequency response of the optimized filter bank.If the filter bank cannot meet the design requirement,its parameters should be changed,and iterative design is used to achieve better clutter suppression.
