利用QAR和DEM的机载气象雷达地杂波仿真方法
Airborne Weather Radar Clutter Simulation Using DEM and QAR
摘要
Abstract
A key factor degrading the performance of airborne weather radar is clutter.Here,the change amount of latitude and longitude is converted into the distance variation to compute electromagnetic scattering of different terrain using a digital elevation model (DEM).The calculation of depression and grazing angle is fixed.According to the meteorological radar equation,the ground clutter is modeled.Radar parameters are set in accordance with the actual parameters of WXR-2100,while flight parameters by the quick access recorder (QAR).The clutter maps for airborne weather radar in the different operating modes are simulated during take-off and cruise stages.The results can reflect actual operating conditions.Finally,the clutter map database is established.关键词
