摘要
机场场面监视雷达主要监视目标为机场场面上的飞机、汽车及跑道异物等。作为一次雷达,其波束照射范围内除有用目标外同时还存在其他无关物体回波,如机场场面上的跑道、滑行道、停机坪、草地、环场路等的表面反射和传输路径上的雨、雾霾的反射回波等。如何在这些无用回波的背景下,可靠地检测并跟踪有用目标是机场场面监视雷达需要解决的重要问题。针对该问题,通过对机场场面监视雷达基本功能的分析,论述了机场场面监视雷达主要杂波的评估方法及相应的反杂波措施。
Surface movement radar（SMR）is used to monitor aircraft and vehicles on the airport surface and other objects on runway.As primary radar,SMR can receive the echoes from other unrelated objects,such as the surface reflection of runways,taxiways,aprons,meadows and the echoes of rain,fog and haze on trans-mission path.How to detect and track useful target within these useless background echoes is an important issue for SMR.In this paper,based on the basic function of SMR,the major clutter and assessment methods for SMR has been discussed and the methods of clutter suppression has been presented correspondingly.
