CFL-03型风廓线雷达收发对接技术的改进

在风廓线雷达的数据应用过程中，雷达获取数据的准确性至关重要，而风廓线雷达的收发对接过程又直接影响获取数据的准确性，因此，对雷达的收发对接技术进行研究非常重要。一般来说，对于该类型风廓线雷达的对接方法采用一种间接测试的方法，对接过程中要反复调整频综脉冲、发射脉冲、收发开关脉冲、封闭脉冲等的波形作用时间和脉宽。另外，收发开关脉冲的后沿并非标准矩形脉冲的后沿，位置难以确定，其后沿设置的位置离发射脉冲太近会产生高频头被击穿烧毁的现象，太远则会影响低层风的测风质量。以CFL-03型风廓线雷达为例，介绍了风廓线雷达的一般收发对接技术和改进的对接技术，以及频综、发射脉冲、收发开关脉冲、封闭脉冲等相关时序的确定方法。经过实践验证，两种对接技术都满足了设备的使用要求，而改进的收发对接技术，更直观形象，易于操作。

Improvement of Transceiver Docking Technology of CFL -03 Wind Profiler Radar

In the process of the wind profiler radar data applications, the accuracy of the acquired radar data is crucial. The transceiver docking process of the wind profiler radar directly affects the accu- racy of the acquired radar data, so studying the radar transceiver docking technology is very important. In general, a kind of indirect test method is adopted for wind profiler radar docking. It should be continually adjusted for the pulse duration and pulse width of the frequency synthesis pulse, the transmitted pulse, the switch pulse, and the closed pulse. In addition, the switch pulse is not a standard rectangular pulse back porch, and the location is difficult to determine. When the switch pulse＇ back porch gets too close to the transmitted pulse, high-frequency head will be broken down, while too far, when it will affect the quality of the low-level wind. In this paper, CFL -03 wind profiler radar as an example, two kinds of concentrated transceiver wind profiler radar docking, a general docking technology, a kind of to improve docking technology, detailedly introduces the frequency synthesis pulse, the transmitted pulse, the switch pulse, the closed pulse and relevant method were introduced. It proved that the two docking technologies both meet the requirement of equipment, and the improved transceiver docking technology is more intui- tive image and easy to operate.
