摘　　要：防风罩作为声雷达的重要组成部分,对声雷达的性能有较大影响。对此,研究声雷达防风罩的高度和倾角对其隔声性能的影响,并针对测试结果进行对比。结果表明,防风罩的倾角越接近声雷达波束发射角度,同时防风罩高度越高,其隔声性能就越好。研究结果能为声雷达防风罩的设计提供参考。As a important part of sodar, windshield has great effect on the performance of it. This paper mainly studies the effect of the size of sodar windshield on sound insulation property, and compared the test results. The results show that sodar windshield has better sound insulation property when the dip angle of windshield was close to beam transmitting angle of sodar and also when the higher the windshield was. The research results can provide reference for the design of acoustic radar windshield.
