| 摘 要： | 预警机具有全空域的远距离探测能力,是现代空战不可缺少的战略装备。首先,推导测量雷达坐标系和目标坐标系在姿态角变换下的转换公式;其次,以苏27 战斗机为例,构建目标全空域的静态RCS数据库,采用准静态法对目标进行动态RCS仿真,大大增加了目标RCS仿真效率,并叠加随机抖动模型修正了姿态角,使数据更加贴近实际,提高了仿真精度。该方法对雷达目标动态特性的研究具有重要的参考价值。

| Abstract: | The AWACS has the Firstly, capability of long-range detection in the whole airspace, and it is an indispensable strategic equipment in modern air combat. Firstly, the conversion formula of the target coordinate system and measurement radar coordinate system under attitude angle transformation are derived. Secondly, taking the case of Su 27 fighter as an example, made a static RCS database of the target over the whole airspace, by using quasi static method for dynamic RCS simulation greatly increases the efficiency of target RCS simulation , and overlying the effect of the random jitter model to correct attitude angle,make the data closer to actual and Improve simulation accuracy. This method has important reference value for the research of the dynamic characteristics of radar target. |
