摘要：
相控多输入多输出（Phased-MIMO）雷达因兼具频率分集阵列 MIMO（FDA-MIMO）雷达的波形分集和距离依赖性优势，同时通过划分发射子阵列而不牺牲相参处理增益，受到越来越多关注。本两部分系列提出一种受频率分集阵列（FDA）雷达启发的电子对抗（ECM）框架，称为 FDA 干扰，评估其对抗机载 Phased-MIMO 雷达的有效性。本部分介绍 FDA 干扰机的原理与类别，并基于 phased-MIMO 雷达的两种情形——相控阵（PA）雷达和 FDA-MIMO 雷达，提出 FDA 干扰信号模型。此外，分析了 FDA 干扰对 PA 和 FDA-MIMO 雷达匹配滤波与空间滤波的影响。数值结果验证了理论分析，并证实所提 FDA 干扰在对抗 Phased-MIMO 雷达方面的有效性。
英文摘要：
Phased multiple-input multiple-output (Phased-MIMO) radar has received increasing attention for enjoying the advantages of waveform diversity and range-dependency from frequency diverse array MIMO (FDA-MIMO) radar without sacrificing coherent processing gain through partitioning transmit subarray. This two-part series proposes a framework of electronic countermeasures (ECM) inspired by frequency diverse array (FDA) radar, called FDA jamming, evaluating its effectiveness for countering airborne phased-MIMO radar. This part introduces the principles and categories of FDA jammer and proposes the FDA jamming signal model based on the two cases of phased-MIMO radar, phased-array (PA) radar and FDA-MIMO radar. Moreover, the effects of FDA jamming on matched filtering and spatial filtering of PA and FDA-MIMO radar are analyzed. Numerical results verify the theoretical analysis and validate the effectiveness of the proposed FDA jamming in countering phased-MIMO radar.
