发表在国际权威会议（IEEE主办）上的美国海军开发的AREPS软件的介绍-AREPS is the U.S. Navy’s designated software tool** for radar performance simulation and analysis. For well over 20 years it has been used to provide accurate propagation predictions in realistic refractive environments for terrestrial radar systems from VHF (~100 MHz) to Q-band (~60 GHz). Recently, the range of pplications for AREPS has been extended by the addition of a communications prediction capability at high frequencies which includes both surface wave and ionospheric sky wave coverage for beyond line-of-sight propagation paths. In this paper we describe the latest

addition to AREPS, which uses refractive height profile input along with a newly developed ray trace capability to provide signal strength estimates for earth-to-satellite communications. By including atmospheric refractivity the model becomes especially useful for determination of antenna pointing angles in strongly refracting environments and for low-elevation satellites for which ray paths through the atmosphere
