在确定雷达系统仿真软件分层设计时,通过对系统分层体系结构进行研究可知激光雷达系统由功能层、系统层、矩阵层共同组成的, 综合仿真软件、建模软件两部分组成其框架。从建模软件的结构来看,嵌入式计算机建模工具是其主要构成部分,除此之外还包括代码自动生成工具、模型生成模块两部分。工具基本模型是由XML模型描述文件创建代码自动生成的,经过转化后,以可执行文件的形式出现;对子系统进行搭建时,嵌入式计算机建模工具起到重要作用,对模型图元采取拖拽的操作,使之进入到建模画布中来,再进行边线操作;对子模型的封装则需要在模型生成模块的作用下完成,并添加到模型树中,满足用户使用需求。将仿真测试应用于软件之中并获取相应的结果,可以确定在文中所设计的嵌入式计算机雷达系统仿真软件功能性较强,可以满足用户模拟和仿真的需求。

Based on embedded computer, the design of lidar system simulation software is studied in this paper. The layered design of radar system simulation software is determined by hierarchical mode architecture. The hierarchical architecture is composed of function layer, system layer and matrix layer, and its framework is composed of comprehensive simulation software and modeling software. The modeling software is divided into embedded computer modeling tool, code automatic generation tool and model generation module. According to the XML model description file, the basic model of automatic code generation tool is created and converted into an executable file; the embedded computer modeling tool drags model elements into the modeling canvas and connects to build the subsystem; the model generation module can encapsulate the sub model and add it in the model tree for users to use directly. The results show that the main modules of the embedded computer radar system simulation software designed in this paper can meet the needs of user simulation and simulation.
