The invention relates to a ground penetrating radar for evaluating the surface state of a runway and estimating the friction coefficient of the runway and a runway surface state evaluation method based on the ground penetrating radar. The ground penetrating radar transmits electromagnetic waves to a runway, and in the propagation process of the electromagnetic waves, the electromagnetic waves can be reflected and refracted at the junction of dielectric layers and be attenuated to different degrees along with different propagation medium densities, different dielectric constants, different electrical coefficients and other reasons. Then, the reflected echos are received, and signal processing is carried out on the attenuation expression of the reflected waves, so that the surface covering layer of the runway is distinguished, and the maximum friction coefficient of the runway is determined according to the material of the surface covering layer of the runway.
本发明涉及一种用于跑道表面状态评估并预估跑道摩擦系数的探地雷达以及基于该探地雷达的跑道表面状态评估方法。本发明基于探地雷达向跑道发射电磁波,在电磁波的传播过程中,它会随着传播介质密度不同,介电常数不同,电性系数差异等原因,电磁波会在介质层交界处发生反射和折射,并且产生不同程度的衰减,通过接受反射回波,并对反射波的衰减表现进行信号处理,从而实现对跑道表面覆盖层的辨别,从而根据跑道表面覆盖层材质确定跑道的最大摩擦系数。
