介绍了大型相控阵雷达天线罩环控系统的重要性,以某地面大型相控阵雷达为研究对象,介绍了天线罩环控系统的指标要求、可行方案、设备构成,论述了环控系统控制策略,对天线罩内的温度场和流场进行了仿真,最终的试验测试与仿真结果一致,满足雷达对罩内空气温度和湿度的要求,为大型雷达天线罩内的环控系统的设计提供了一种可行方案。

The importance of the environment-control system for the large scale phased array radar radome is described in this paper. Then, with one large scale phased array radar as an example, the key points of its designing, including parametric demands,an executable scheme, contents, and illustrates the control strategy is introduced in detail. In addition, to achieve a delicate flow pattern inside the radome, a flow pattern is engineered with the aide of computational-fluid-dynamics numerical simulation, which is eventually experimentally validated to favor the uniformity of air temperature inside the radome. In conclusion, a practical scheme is provided for the design of the environment-control system for the radome-covered large scale radars.
