摘要
摘要:针对复杂环境下对低可观测运动目标探测的迫切需求，该文在系统回顾近几年频控阵雷达国内外发展现状、频控阵雷达阵列结构设计及波束形成、距离和角度的联合估计等技术的基础上，提出了基于空距频聚焦的频控阵雷达信号新方法。充分利用频控阵雷达提供的发射波形自由度、阵元位置自由度、波束方位与距离相关性以及凝视观测的特点，即在空间(角度)、距离和频率(多普勒)的灵活自由度和能量集性，实现空-距-频聚焦和联合参数估计。仿真分析表明该方法具有提高复杂环境下雷达微弱动目标检测和参数估计的潜力，在杂波和干扰抑制、动目标精细化处理等方面有广阔的应用前景。

Abstract:To meet the urgent demand of low-observable moving target detection in complex environments, a novel method of Frequency Diverse Array (FDA) radar signal processing method based on Space-Rang-Doppler Focusing (SRDF) is proposed in this paper. The current development status of the FDA radar, the design of the array structure, beamforming, and joint estimation of distance and angle are systematically reviewed. The extra degrees of freedom provided by FDA radar are fully utilizsed, which include the Degrees Of Freedom (DOFs) of the transmitted waveform, the location of array elements, correlation of beam azimuth and distance, and the long dwell time, which are also the DOFs in joint spatial (angle), distance, and frequency (Doppler) dimensions. Simulation results show that the proposed method has the potential of improving target detection and parameter estimation for weak moving targets in complex environments and has broad application prospects in clutter and interference suppression, moving target refinement, etc..
