数字阵列MST雷达是有源相控阵气象雷达,可探测中层、平流层和对流层的大气风场。该雷达采用了分布式全固态 发射技术以及数字波束形成技术,减少了硬件的复杂性,提高了探测性能,更适用于复杂天气过程的探测。幅相标校技术 是数字阵列MST雷达的关键技术之一,该技术可以提高雷达的幅相一致性,从而提高雷达的探测性能。文中首先介绍了 数字阵列MST雷达的系统组成,然后采用了矩阵分析的方法推导了幅相标校算法,给出了幅相标校系统设计流程,最后得 出了一组实际标校结果。

The digital array MST radar is an active phased-array meteorological radar, which measures winds in middle-atmosphere, stratosphere and troposphere. The radar applies distributing solid transmitter technology and digital beamforming technology, which can decrease the complexities of hardware, and improve the capability of radar, also adapt to the exploration of complex weather processes. The technology of amplitude and phase calibration is one of the key technologies to digital array radars, which can improve the amplitude-phase consistence of radar, and can also improve the capability of radar. The composition of the radar is presented at first, and the method of amplitude and phase calibration is discussed with matrix analysis,and then a design of amplitude and phase calibration system is given, at last a true result is given.
