摘要
近年来,米波雷达因其在反隐身目标方面所体现出的优势而引起了雷达界的高度重视,新型米波雷达不断问世。主要用于警戒雷达的米波频率较低,因而雷达天线结构比较稀疏,天线阵面巨大,并且大多部署在沿海或沙漠、戈壁地区,环境条件恶劣,风力往往比较大。因此米波雷达天线车的安全性设计尤为重要,而天线车的抗倾覆能力又是安全性设计的重中之重。文中给出了某型号车载米波雷达风负载的计算方法及给定环境条件下天线车的抗倾覆能力,并对抗倾覆能力的检验方法作了简要的介绍,通过实验验证了计算方法的可靠性。
Recently,VHF radar has got great attention by radar research world because of its advantages on target anti-stealth,and new type radars have been produced ceaselessly.Used mostly for surveillance,the frequency of VHF radar is relatively low,so its antenna structure is usually huge and sparse.Most of these radars are disposed in coastal and desert area where is of severe natural environment and great wind force.Therefore,safety design of VHF radar antenna vehicle is especially important,and the overturn-resisting ability of the vehicle is of top priority.This paper introduces the calculation methods of wind load for one VHF radar vehicle and the vehicle overturn-resisting ability under given environment conditions,and briefly describes the test methods for overturn-resisting ability.Reliability of the calculation methods is validated through experiments.
