摘　　要：在常用雷达地杂波反射率模型的基础上,综合考虑雷达频率、地形种类和入射余角等对地杂波反射率的影响,建立了一个低入射余角下雷达地杂波反射率模型,并在不同的情况下,该模型与其他常用地杂波反射率模型相比较。结果表明:该雷达地杂波反射率模型更符合实际,进而证明了该模型的有效性和实用性。A reflectivity model is presented for radar land clutter at low grazing angle.The model takes into account into radar work frequency,terrain type and the grazing angle.The model absorbs the merits from commonly used reflectivity models of land clutter;it introduces several researchers' opinions,and extends them;it accounts for the reflectivity with arbitrary radar frequency from VHF to X-band,arbitrary common terrain and arbitrary low grazing angle.The reflectivity obtained with our model compares.Favorably with statistically experimental data obtained under conditions similar to those modeled.
