| Radar in war now has been playing an important role, especially for the Vehicle Motion Radar. Because of the high degree of informationization in battlefield nowadays and the mobility of the Vehicle Motion Radar.These advantages established it in modern warfare an irreplaceable position. The radar concealed performance is good, a high degree of automation, so it has a high frequency of using in the war, so more and more countries have invested more and more money to the military equipment research and to develop it.In this paper, the research is based on a certain type of Vehicle Motion Radar. Simplified model of radar antenna is conducted, the 3d Navier-Stokes equation as the foundation, based on the finite volume method, and the density meter is designed algorithms, use Roe format solution model of radar antenna for the wind load effect of the simulation. According to the existing shrinkage first wind tunnel data, numerical simulation is compared with wind tunnel experiments data, and parameter is improved. Later apply it to another radar antenna model for simulation. Wind pressure of three direction of force and torque data are obtained. The analysis result could apply technical support for the Vehicle Motion Radar and could provide the valuable reference data for engineering application. |
