摘要
脉冲重复频率(Pulse Repetition Frequency,PRF)是弹载合成孔径雷达(弹载SAR)的一个重要成像参数。弹载SAR的PRF设计需要考虑多种因素,本文考虑了雷达威力、方位向波束宽度对PRF的约束,提出了基于这两个参数的一种改进的PRF设计方法。该设计方法在满足系统指标(图幅宽度、分辨率等)的要求的前提下,可根据弹载SAR的位置信息动态的选择合适的PRF值。本文通过仿真实验进一步证明了该方法的有效性和可行性。
Pulse repetition frequency(PRF)is an important imaging parameter of missile-borne synthetic aperture radar(SAR).There are many factors to be considered in the PRF design of missile-borne SAR.In this paper,the constraints of radar detection capability and azimuth beamwidth on PRF is taken into consideration,based on which an improved PRF design method is proposed.The proposed method can dynamically select appropriate PRF values according to the location information of the missile-borne SAR with required system specifications(map width,resolution,etc.)being met.The simulation results prove the effectiveness and feasibility of the proposed method.
