摘要
保证在飞机探测性能不受损失的前提下,尽可能真实提取气象的强度和多普勒信息,是航管一次监视雷达气象通道的设计难点。本文叙述了航管一次雷达气象通道的现状和发展趋势,分析了在兼顾飞机探测的同时气象通道设计中存在的主要问题,并针对气象强度信号的处理提出了一些解决方法。
For design of weather channels in ATC primary surveillance radar (PSR), it is difficult to obtain the weather intensity and Doppler information as true as Possible without loss of the performance of detection of airplane. This paper depicts the current state and developing trends of the weather channels in PSR for ATC,analyses the main problems in weather channels design,and discusses some methods for weather-intensity signal processing.
