机场跑道异物(ForeignObjectDebris,FOD)目标所处环境雷达杂波背景较为复杂且相对较强,因此,需使用恒虚警(CFAR)技术,以获得满意的检测性能。针对此问题,通过计算机Matlab仿真模拟机场跑道FOD检测应用环境,对几种CFAR方法的性能进行了分析和比较,总结出几种方法的优缺点,为实际工程应用提供了理论依据。
The radar clutter background that airport runway FODs (Foreign Object Debris) situate is complex and relatively strong,therefore,constant false alarm rate (CFAR) technology is used to obtain satisfactory detection performance.Focus on this prob- lem,application of FOD detection in airport runway environment is simulated by Matlab.Simulations of some CFAR methods are per- formed, and simulation results are compared, which provides theoretical basis for practical engineering application.
