摘　　要：机载气象雷达作为一种重要的气象监测手段,被广泛应用到国防和民用,它能够通过间歇的接收云层中粒子的散射回波来实时远方的气象状况,保证飞机的安全飞行。相控阵雷达作为目前功能最为强大的雷达,它不仅能通过多普勒效应检测到能检测到气象目标的位置、强度、运动方向和内部粒子活跃程度,而且其波束可以快速捷变,能够对气象目标区域进行全空域扫描,因此机载相控阵雷达在气象检测方面有着突出的优势。本文在相控阵雷达上,采用MTI杂波对消和脉冲对算法实现了气象目标检测,并对其在实测数据上的效果进行了详细分析。实验结果表明,本文的方法能够准确地检测到气象目标的位置和强度,并且计算量小,工程化容易,因此具有重要的研究意义和较大的应用价值。As an important means of meteorological monitoring,airborne weather radar is widely used in national defense and civil use.It can ensure the safe flight of the aircraft by intermittently receiving the scattering echo of the particles in the cloud to achieve real-time remote meteorological conditions.As the most powerful radar at present,phased array radar can not only detect the position,intensity,motion direction and internal particle activity of meteorological targets through Doppler detection,but also its beam can be changed quickly and can scan the whole airspace of meteorological target area.Therefore,airborne phased array radar has outstanding advantages in meteorological detection.In this paper,the meteorological target detection was realized by using MTI clutter cancellation and pulse pair algorithm on phased array radar,and its effect on the measured data was analyzed in detail.The experimental results showed that the proposed method can accurately detect the location and intensity of meteorological targets,cost low and be easy to be engineered.Therefore,it has important research significance and great application value.
