摘要
研究了相控阵雷达数据率参数随着所测目标距离不同而产生的变化情况。相控阵雷达一般工作在边搜索边跟踪的状态,其数据率可分为搜索数据率和跟踪数据率。本文以卡尔曼滤波跟踪算法为例,重点讨论了跟踪数据率随采样时间和所测目标距离的变化趋势。进行了计算机仿真,实验结果能够反映出相控阵雷达数据率参数的特点。
The data rate factor changing of phased array radar with the distance of target is discussed. Phased army radar is working most at track-while-scan(TWS). Its data rate factor can be separated scan data rate factor and tracking date rate factor. With the Kalman filter as an instantiation, the changing of the data rate factor along with sample time and distance of target is studied. The result of computer simulation can reflect the data rate factor's characteristic.
