摘要
解距离模糊和解速度模糊是中重复频率脉冲多普勒雷达中需要解决的重要问题 ,其算法的依据都是中国余数定理。但是 ,单靠中国余数定理仍无法解决距离测量和多普勒频率测量中的误差和遮挡问题。本文讨论了在测量误差和遮挡问题存在的情况下解距离模糊所采用的建表搜索法和解速度模糊所采用的各模糊度内最小方差过门限法 ,并将这两种算法与其他算法进行了对比。
Resolution of range and velocity ambiguities is the most important problem in medium PRF(MPRF) pulse doppler radar. The theory of the ambiguity resolution algorithms is Chinese Remainder Theorem. But the Chinese Remainder Theorem cannot solve the error and the blind region made in range and doppler velocity measurements. The table searching method for range ambiguity resolution and the least squared error overthreshold method for doppler ambiguity resolution are discussed in this paper, and the comparison between the two algorithms and other algorithms is presented. The suggested algorithms have important value in practical application.
