摘　　要：在对某型导弹控制箱的性能参数进行检测时,模拟飞行中的导弹陀螺所产生的弹体旋转信息信号是必不可少的条件。在对DDS(Direct Digital Synthesis,直接数字频率合成)原理分析的基础上,通过改进,给出了FPGA设计方案,用QuartusⅡ软件对系统进行了仿真,用Altera公司的FPGA—EP2C35F672C6N对系统进行了硬件实现。实验结果表明,系统能够精确地模拟导弹在不同转速下所产生的陀螺信号,信号周期误差在10ns以内,所产生的信号经调理电路送控制箱后能够被控制箱正确识别。When checking the performance parameters of the control instrument of a type of missile,it is necessary to simulate the signal of the missile rotation information generated by the gyro of the flying missile.A solution is provided using FPGA by analyzing on the principle of DDS.Quartus II software is used to simulate and the FPGA—EP2C35F672C6N is used to apply the system.The results show that the system can simulate the signals of rotation information generated by the gyro precisely when the missile rotates on different speed,and the error of every cycle is within 10ns.The signal simulated can be recognized by the control instrument correctly after being conditioned.
