| 摘 要： | 针对小斜视角下单发多收(SIMO)雷达对空运动目标单次快拍成像时天线数目较多的问题,提出了一种稀疏空域SIMO雷达运动目标成像方法。首先详细分析了小斜视角下SIMO雷达单次快拍成像原理,其次结合压缩感知理论具体阐述了小斜视角下稀疏空域SIMO雷达运动目标成像方法。该方法不仅能够对运动目标实现单次快拍成像,避免了非合作运动目标强加速、大转角等引起的运动补偿难题,同时又能够大幅减少接收天线单元数,便于工程实现。最后利用仿真实验验证了文中方法的有效性和可行性。

| Abstract: | The number of antenna elements of single-input multiple-output(SIMO) radar is too many when imaging for moving target with single snapshot.To solve the problem,a new imaging method of moving target for sparse spatial SIMO radar with small-squint angle is proposed by this paper.Firstly,the single snapshot imaging method for SIMO radar with small-squint angle is analyzed in detail.Then,the imaging method based on Compressive Sensing(CS) for sparse spatial SIMO radar with small-squint angle is put forward.Sing... |
