针对海防雷达部队训练无目标模拟器导致的训练效果不理想问题，提出了研制海防雷达目标模拟器的解决方案。软件算法部分，在分析海杂波分布特性的基础上，首先利用杂波模拟技术仿真生成海浪杂波，其次基于SwerlingIV模型生成目标回波，然后利用叠加模型生成带杂波的海面目标回波，完成目标回波的模拟仿真工作。硬件上提出CPLD+DSP的解决方案，CPLD完成系统的时序及逻辑控制，DSP将模拟仿真信号实时生成目标回波。相关部门实际使用结果证明了该方案的有效性。

Since the training effect of sea defense radar troops is unsatisfactory caused by the fact that there is no target simulator for the training,a scheme to develop the target simulation system is put forward to resolve the problem. In the software algorithm,the sea clutter is generated with cluster simulation technology based on characteristic analysis of the sea clutter. The target echo is generated based on the Swerling IV model,and then the sea-surface target echo with sea clutter is generated by means of the overlay model to finish the target echo simulation. As for the hardware,the solution of CPLD+DSP is put forward. CPLD is used to accomplish the time sequence and logical control. DSP is used to create the target echo from the simulation sig-nal. The actual use of this system validates the efficiency of this system.
