摘　　要：中小功率容量的微波吸收负载已成为雷达工程中剩余功率和反射功率吸收、损耗的关键器件。针对内循环制冷系统,研制了一款基于高温水泥渗铁粉且末端开口风阻小的功率负载。该负载较传统负载具有价格低廉、制作方便、结构紧密等优点,已用于航天测控系统地面装备的某雷达工程。Microwave absorption load with small and medium power has become a key part for surplus power and reflec-ted power absorption and loss in radar engineering. In this paper, a power load with properties of high temperature cement mixed iron powder, open ended and wind resistance has been designed for the circulating cooling system. Compared with conventional loads, this load has the advantages of low cost, easy production and compact structure. It has been applied to radar engineering.
