摘要
研究了脉冲多普勒气象雷达中用于解速度模糊的交错脉冲方法 ,理论分析了时域脉冲对处理中速度估计公式的局限性 ,同时对该公式进行了修正。仿真结果表明 ,改进的交错脉冲方法具有更好的解速度模糊性能 ,而且易于实时处理。
The staggered pulse method for resolving velocity in pulse doppler (PD) weather radar is studied and a modified version is presented through strict mathematical analysis. The simulations reveal that the modified method has more robust velocity measurement performance and wider velocity measurement range. Moreover, this improved method can be easily used in real-time signal processing.
