摘　　要：为了有效降低海杂波对船舶导航雷达工作的影响,提出了一种基于二阶锥规划(SOCP)理论的杂波抑制算法。针对传统的实系数有限冲激响应(FIR)数字滤波器组无法保证通带群延时(小数)精度的问题,通过将初始优化问题转化为对偶问题进行求解,利用SOCP理论的分布式计算优势,稳定有效地求取其局部最优点,同时用重构的海杂波样本反复训练理论模型。通过仿真实验证明SOCP理论可以更好地重构信号检测模型,大幅抑制海杂波的影响,提高船舶导航雷达的目标检测能力。In order to effectively reduce the impact of sea clutter on the operation of marine navigation radar,a clutter suppression algorithm based on the second order cone programming(SOCP)theory is proposed.In response to the problem that traditional real coefficient finite impulse response(FIR)digital filters cannot guarantee the accuracy of pass band group delay(decimal),the initial optimization problem is transformed into a dual problem for solving.By utilizing the distributed computing advantages of SOCP theory,the local optimal point can be stably and effectively obtained,and the theoretical model can be repeatedly trained by using reconstructed sea clutter samples.Through simulation experiments,it is proved that the SOCP theory can better reconstruct the signal detection model,significantly suppress the influence of sea clutter,and improve the target detection ability of marine navigation radar.
