摘要
描述一种被称为SZ相位编码的解距离模糊方法在脉冲多普勒气象雷达中的应用.首先给出了该方法应用到某气象雷达上所采用的系统框图;然后介绍了SZ相位编码的原理和编码序列以及基于这种编码给出了气象雷达解距离模糊算法的详细流程,并着重介绍了频谱重构的频域处理方法;最后给出了用该方法同时解出一次和二次气象回波的Matlab仿真,结果表明该方法对平均速度的估算较为准确.
A method of phase code named SZ code to mitigate range ambiguity applied on a pulse Doppler weather radar is introduced. The system chart of designing a weather radar with SZ phase code is listed, the principal and coding series of this kind of SZ phase code is illustrated. The flow chart of its algorithm that can be applied to a weather radar is introduced, and the processing method of reconstruction of spectrum is mainly stated. Finally recovering both first and second weather echo using this kind of method is simulated and the result shows that it is a good method to estimate mean velocity accurately.
