摘要: 該文以彈道導(dǎo)彈防御為背景，研究在有預(yù)警信息條件下相控陣?yán)走_(dá)監(jiān)視空域的問(wèn)題。首先討論了無(wú)先驗(yàn)指示信息條件下相控陣?yán)走_(dá)監(jiān)視空域，然后在分析彈道預(yù)報(bào)及其精度的基礎(chǔ)上，給出了小窗口位置和半徑的遞推算法以及坐標(biāo)轉(zhuǎn)換公式，建立了基于彈道預(yù)報(bào)的戰(zhàn)術(shù)相控陣?yán)走_(dá)小窗口監(jiān)視空域模型，并且與全空域搜索比較了檢測(cè)性能，最后進(jìn)行了仿真驗(yàn)證。Abstract: 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.
