摘　　要：随着现代军事电子技术的迅速发展,来袭目标经常是机动性很强的变速动目标,其目标多普勒随时间变化,常规的空时自适应处理方法对于这类目标的检测效果很差。文中提出了一种基于修正最优处理器的机载变速动目标检测方法。该方法采用修正的导向矢量对多普勒走动项进行补偿,因此能够在目标存在多普勒走动的情况下,获得满意的动目标检测结果。仿真结果表明,该方法能够增强机载雷达对变速动目标的检测能力。With the rapid development of modern military electronics technology, the attracking targets are highly maneuverable. The target with highly maneuverability is hard to be detected employing the conventional STAP for time-varying target Doppler frequency. In this paper, a method of maneuvering target detection based on the modified optimal processor is presented. The method applies the modified steering vector in compensating Doppler migration, which can detect the target with Doppler migration efficiently. Simulation results demonstrate that this method can enhance the maneuvering target detection capability of airborne radar.
