| 摘 要： | 为了提高检测性能和实现多功能 ,PD雷达常采用高、中、低脉冲重复频率 PRF。对应一定的脉冲重复频率 ,PRF会出现测距模糊、测速模糊。以聚类算法为基础 ,本文介绍了一种用于雷达目标解距离、速度模糊的滑窗相关器算法。该滑窗算法是一种遍历性的算法。文中对该算法的解模糊正确率、运算效率进行了讨论 ,分析了解模糊正确率与脉冲重复频率 PRF、检测范围、滑窗宽度间的关系 ,同时给出了仿真结果。

| Abstract: | For enhancing performances and increasing functions of PD radar, High PRF, medium PRF and low PRF are commonly applied into system ambiguity appeared in range and velocity in some PRF. Based on clustering, a sliding window correlator algorithm for resolving the radar object ambiguity in range and velocity is described. Slide window algorithm is a searching algorithm. The probability of ambiguity resolution for targets and the computational efficiency are discussed. The relations between the probability of ambiguity resolution of this algorithm and PRF, the range of interest, and the width of sliding window are analyzed. Simulational results are also given. |
