摘　　要：为了加快亚轨道飞行器再入段导航制导系统从算法设计到硬件产品的实现过程,采用快速原型技术进行设计。借助基于RTX的快速原型开发平台,利用Matlab/Simulink/RTW将导航制导模型自动生成C代码,对自动生成代码做出相应修改以满足系统实时性要求,再编译链接生成可执行DSP代码,加载到DSP(数字信号处理器),实现了亚轨道飞行器再入段导航制导系统的DSP硬件在回路仿真。该系统的实时仿真结果与Simulink数字仿真结果一致,表明快速原型系统设计的正确性。该方法具有开发周期短、实时性能好等优点。In order to speed up the Suborbital Launch Vehicle re-entry navigation guidance systems from algorithm design to hardware implementation of the process,the Rapid Prototyping technology is used to design the system.Using this RTX-based Rapid Prototyping development platform and Matlab/Simulink/RTW,turn navigation-guidance model into automatically generation of C code,and modify these codes to satisfy the real-time demand of system,then link through the CCS compiler to generate executable DSP code that loaded into the DSP,which has achieved the Suborbital Launch Vehicle re-entry navigation and guidance system of DSP hardware-in-Loop Simulation.The results of real-time simulation and numerical simulation results are consistent,which proves the Rapid Prototyping design is correct,and it also has merits such as shorter development cycle,excellent real-time performance.
