空间目标双基地雷达 ISAR 成像技术研究

摘要

Because of the particular advantage of bistatic radar,it is becoming the key factor in modern radar field.It is very important to research bistatic radar space target ISAR imaging for space surveillance and early warning.In this paper,the bistatic radar system design which fits for space target ISAR imaging is carried out by analyzing the principle of bistatic radar and ISAR imaging and computing the key parameters of bistatic radar system.Finally,according to the radar real data,the design correctness and the technical feasi-bility are verified.Which will be very useful and effective in future bistatic radar ISAR imaging.%由于双基地雷达在复杂电磁环境中的独特优势，日益成为现代雷达研究的热点之一。通过构建双基地雷达系统，开展空间目标双基地 ISAR 成像技术研究对空间监视、探测识别等技术有非常重要的战略意义。通过对双基地雷达的工作原理、ISAR 成像原理、系统关键参数等分析计算，实现了双基地 ISAR 成像系统设计，并利用现有系统构建了双基地雷达，开展双基地 ISAR 成像技术研究，利用实际试验数据进行了技术验证，结果表明双基地雷达 ISAR 对空间目标成像的可行性及其系统成像效果的良好性。
