在PD雷达中距离和速度模糊不可避免,为解模糊需要发射多重频脉冲串。该文引入一种高效的模糊分辨新算法,运算简单、计算量小、精度高、易于实时处理。利用该算法在实现模糊分辨的同时能获得好的估计性能。设计实例及数字实验说明了该方法的正确性和有效性。该算法也可用于欠采样、多基线干涉仪测向或其他类似系统进行频率、方向等参数的模糊分辨。

Generally, range and velocity ambiguity existin pulse Doppler （PD） radars Multiple pulse recurrence frequency （PRF） is needed for resolving ambiguity in the conventional PD radars. This paper provides a technique to resolve the ambiguities with high performance, which is a computationally efficient algorithm and easy to process in a real-time mode. It is able to achieve range and velocity estimates with high precision besides resolving ambiguity by the use of the presented technique, An example and corresponding experimental results show the correctness and validity of the introduced approach. This technique can be also used in sub-Nyquist sampling and interferometer-like with multiple baselines, or others homologous systems to increase their scopes of unambiguous measurements and resolve ambiguities.
