本文分析了双重复频率退模糊方法的局限性和误差成因,提出了一种统计求解方法进行速度退模糊。此方法同传统方法的差异在于,其首先对Nyquist数进行估计,再进行退模糊处理。理想实验和在中频相参多普勒天气雷达上的实际结果分析均表明,改进的方法具有更好的解速度模糊性能,且具有较高的实效性。 This paper analyzes the limitations and error causes of the double complex frequency retreat method, and proposes a statistical solution method for velocity retreat. The difference between this method and the traditional method is that it first estimates the Nyquist number and then performs the defuzzification process. The results of the ideal experiment and the actual results on the mid-frequency coherent Doppler weather radar show that the improved method has better performance of solution velocity fuzzing and has higher effectiveness.
