摘　　要：研究了信噪比对角跟踪的影响,针对相参体制的雷达,给出了在强海杂波背景下有效跟踪海面上低速运动目标的具体方法,并在基于ADSP 21161N的信号处理平台上实现了该算法。它利用多个回波脉冲作相参积累有效地改善了提取角误差的条件,即提高了雷达回波信噪比,大大提高了跟踪的稳定度和精度。仿真结果验证了它的有效性。The influence of SNR on angle tracking is studied. In the case of strong sea clutter is provideds, and the method on the signal processing platform based on acking ADSP-21161N is implemented. This method can effectively improve the condition (i.e SNR of returning wave) for extracting angular error by integrating multiple coherent returning waves and greatly improve precision and stabilization of angle tracking. Simulation results confirm the effectiveness of this method.
