弹载相控阵雷达系统设计与信号处理问题

摘要

弹载相控阵雷达的系统设计与信号处理实现低空目标探测是下一代主动雷达导引头的一项关键技术. 针对这些问题, 本文从技术难点、 工作模式等方面对导引头雷达动目标检测进行了分析. 相比机载预警雷达, 弹载雷达采用前视阵列且运动速度快、 工作波长短, 杂波存在距离、 多普勒多重模糊问题, 杂波特性严重非均匀, 杂波抑制难度大. 本文给出了笔者在弹载雷达系统设计及空时自适应处理方面所做的工作, 同时指出了目前这一领域有待改善和研究的相关问题.%The system design and signal processing of missile-borne phased array radar to realize low-attitude target detection is a crucial technology in the next generation of air-to-air guided missile.Focus on this technology, a detailed analysis on moving target detection covering the technical difficulties, working mode and so on is provided.Compared with early airborne warning radar system, the speed of missile-borne radar is fast and the working wavelength is short.And forward-looking array is often adopted in missile-borne radar system.Therefore, the clutter has the problem of range and Doppler ambiguity, the clutter characteristic is non-homogeneous and its suppression is difficult.In this paper, some of latest works done by author are introduced, and some of relative problems to be studied are listed.
