基于弹道预报的相控阵雷达监视空域研究

该文以弹道导弹防御为背景，研究在有预警信息条件下相控阵雷达监视空域的问题。首先讨论了无先验指示信息条件下相控阵雷达监视空域，然后在分析弹道预报及其精度的基础上，给出了小窗口位置和半径的递推算法以及坐标转换公式，建立了基于弹道预报的战术相控阵雷达小窗口监视空域模型，并且与全空域搜索比较了检测性能，最后进行了仿真验证。

Surveillance Volume of Phased Array Radar Based on Trajectory Prediction

The surveillance space of Phased Array Radar(PAR) supported by early warning system is studied in the paper under the background of Ballistic Missile Defense(BMD). Firstly, surveillance space of PAR without prior indication information is discussed. After analyzing the trajectory prediction and its precision, the recurrence algorithms for positions and radiuses, and coordinates transformation are presented, and the small-window surveillance spaces model for PAR based on trajectory prediction is established. Additionally its detection performance is compared with whole-space searching. Finally, the model is demonstrated using simulation.
