论文摘要
本文开发了用于天气雷达系统的脉间间频率多样性方案。它建立了将其与天气雷达系统中的其他脉冲间计划进行比较的频率多样性技术的性能。脉冲间编码被广泛用于第二次跳闸抑制或交叉极化隔离。在这里，讨论了一种新的脉间方案，利用频率各种波形。评估了性能的模拟和测试，请记住NASA双频，双极化，多普勒雷达（D3R）。描述了一种新方法，可以恢复由于频率脉冲变为脉冲的变化样品的不连贯而导致的速度和光谱宽度。与流行的系统相位代码相比，该技术可以在其他旅行污染的动态范围更高的动态范围内恢复天气雷达矩，以进行第二次旅行抑制和检索。
This paper develops the use of Inter-pulse frequency diversity scheme for a weather radar system. It establishes the performance of frequency diversity technique comparing it with other inter-pulse schemes for weather radar systems. Inter-pulse coding is widely used for second trip suppression or cross-polarization isolation. Here, a new inter-pulse scheme is discussed taking advantage of frequency diverse waveforms. The simulations and tests of performance are evaluated keeping in mind NASA dual-frequency, dual-polarization, Doppler radar (D3R). A new method is described to recover velocity and spectral width due to incoherence in samples from change of frequency pulse to pulse. This technique can recover the weather radar moments over a much higher dynamic range of the other trip contamination as compared with the popular systematic phase code, for second trip suppression and retrieval.
