【摘要】：以临近空间高超声速目标防御为背景,研究了无引导信息下远程预警相控阵雷达搜索能力问题。针对临近空间工作模式,深入分析了雷达搜索屏、脉冲宽度、信号周期、搜索帧周期等搜索参数的设计原则和确认方法,分析了脉冲宽度随波束指向变化补偿关系,推导了目标不同高度仰角穿屏的最短穿屏距离和雷达捕获目标的最小扫描次数,以HTV-2为例仿真分析了雷达的探测能力,结果表明当目标迎面来袭时雷达具备完全的捕获能力,当目标从后方顶空来袭时为捕获目标需要采取TWS模式。
[Abstract]:Based on the hypersonic target defense in near space, the search ability of remote early warning phased array radar without guidance information is studied. The radar search screen, pulse width and signal period are deeply analyzed for the near space operation mode. The design principle and confirmation method of searching parameters such as frame period are analyzed. The compensation relationship between pulse width and beam direction is analyzed. The shortest penetration distance of target at different elevation angles and the minimum scanning times of radar capture target are deduced. Taking HTV-2 as an example, the detection ability of radar is simulated and analyzed. The results show that the radar has complete capture capability when the target is coming head-on, and the TWS mode is needed to capture the target when the target is coming from the rear headspace.
