【摘要】：在高脉冲重复频率多普勒雷达的工程应用中,存在着无法避免的距离模糊问题。提出了一种基于Lattice的解距离模糊新算法。首先给出了距离模糊问题的数学模型,将距离模糊问题转化为Lattice中求解最近点的问题;然后证明了模型满足Babai算法的使用条件,提高求解效率;接着针对脉冲重复周期提出了扩倍的处理方案,放宽了算法对于雷达参数的要求;最后结合Lattice中Voronoi单元的基本性质提出了噪声补偿方案,根据模糊量测的整数部分和小数部分补偿出真实的量测整数部分的组合,使算法具有工程可行性。实验仿真表明,该算法可以同时满足时间效率和求解精度的要求。
[Abstract]:In the engineering application of high pulse repetition frequency Doppler radar, there is an unavoidable range fuzzy problem. A new range fuzzy algorithm based on Lattice is proposed. Firstly, the mathematical model of range fuzzy problem is given. The distance fuzzy problem is transformed into the problem of solving the nearest point in Lattice. Then it is proved that the model satisfies the conditions of the Babai algorithm and improves the efficiency of the solution. Finally, combining with the basic properties of the Voronoi element in Lattice, the noise compensation scheme is proposed, and the combination of the real measurement integer part and the integer part is compensated according to the integer part and the fractional part of the fuzzy measurement. The experimental results show that the algorithm can meet the requirements of both time efficiency and accuracy.
