摘要
以Matlab/simulink为工具,对相位干涉仪快速准确获取窄脉冲目标雷达的角信息问题进行了仿真研究。研究表明,相位干涉仪快速、准确获取窄脉冲目标雷达角信息的基本能力主要取决于鉴相器中低通滤波器截止频率的设计,并给出了截止频率的设计公式。此外,还对读取相关信息的时机和方法等问题进行了研究,给出了相应的解决方案。
In this paper, the problem of acquiring angle information of narror pulse radar with phase interferometer rapidly and exactly is researched by simulating with Matlab/simulink. The research shows that the basic capacity of phase interferometer acquiring angle information of narrow pulse radar rapidly and exactly come mainly from the stop frequency of the low pass filter of the phase detector. The design formula for the stop frequency is given. In addition, the problems of time and method for reading the correlative phase information are researched and the corresponding resolving schemes are get.
