摘要
提出了一种基于分布式星载单脉冲雷达的地面动目标检测方法,该方法充分利用星载分布式雷达主瓣和栅瓣回波的空时二维分布特点,能够在一次扫描(一个相干处理间隔)中有效地检测和分辨不同栅瓣杂波中的地面低速动目标,因此该方法不仅具有比一般分布式星载雷达处理更大的区域覆盖率和广域监视能力,具有较高的GMTI性能,且处理简单,运算量低,适合于星上实时处理.
A ground moving target indication（GMTI） method for distributed space-based monopulse radar is proposed.This method takes advantage of the space-time distribution of the mainlobe and gratelobe echoes of distributed space-based monopulse radar,and can detect targets buried in gratelobe clutters during one coherent processing interval（CPI）,thus more area coverage rate（ACR） and higher wide area surveillance ability can be achieved.It＇s shown that this method is also computation-saving and is very suitable for on-board processing.
