动态RCS测量的信号仿真

摘要

A signal simulation system for RCS dynamic measurement is developed and designed based on the Microsoft SQL Server 2005 database management system,ADO.NET database access technology and Visual Studio 2008 development environment.It is built on the C/S（client/server） structure.It can store and manage radar cross section（RCS） simulation data for each radar target in the database.The trajectories of horizontal straight flying,radial flying and spiral flying are calculated by means of kinematics equations.The inevitable random wobble in the flight is taken into consideration and the results of the real time RCS with different poses and radar echoes are presented.The system achieves the goal of signal simulation for RCS dynamic measurement finally.The system designed in the paper has prevalent applicability.It can be used in different radars and different targets for dynamic measurement processing.%基于Microsoft SQL Server 2005数据库管理系统、ADO.NET访问数据库技术和Visual Studio 2008开发环境,采用C/S（客户端/服务器）结构,开发了动态RCS测量的信号仿真系统。该系统能够存储和管理多个雷达目标的雷达散射截面（RCS）仿真数据,利用运动学方程仿真了目标在横向直行、径向直行以及盘旋运动轨迹下的机载姿态数据,且考虑了飞行过程中不可避免的随机扰动,最终计算得出不同时刻、姿态下目标的RCS、雷达回波数据,实现了动态RCS测量原始数据的仿真。该系统具有普适性,可以在不同雷达与目标的动态测试仿真中应用。
