To improve radar interception performance and image resolution, we propose a signal design and processing approach for multiple input multiple output (MIMO) radar that employs stepped orthogonal frequency division multiplexing (OFDM) to detect small UAVs. First, the proposed...
为了提升雷达的低截获性能和成像分辨率,本文提出了一种基于步进正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)的多输入多输出(Multiple Input Multiple Output,MIMO)雷达信号设计和处理方法。该方法是将窄带OFDM信号与非线性步进方案相结合,通过非线性步进方案控制MIMO发射信号的载频,获得发射端正交波形和大...
