摘　　要：文中介绍一种多天线海冰接收机的整体架构以及其在多极化海冰探测领域的应用。在此基础上系统描述其软硬件的设计,给出直射通道、反射通道和控制系统的详细设计方案及具体实现。针对“北斗三号”B1C新信号的特点,设计并实现一种利用“北斗二号”B1I信号辅助“北斗三号”B1C反射信号处理的方法。最后进行反射信号接收的初步试验,在试验中接收到不同极化的反射信号,并通过上位机软件观察其相关功率,同时对比B1C与B1I反射信号的相关结果,验证设备可以正常工作。The overall architecture of multi⁃antenna sea⁃ice receiver and its application in the field of the multi⁃polar sea⁃ice detection are introduced.On this basis,its hardware and software design are described systematically,the detailed design scheme and concrete realization of the direct channel,reflection channel and control system are given.In allusion to the characteristic of the new signal B1C of the BeiDou navigation satellite system 3(BDS⁃3),a method using BeiDou⁃2 B1I signal to assist BDS⁃3 B1C reflected signal processing is designed and implemented.The preliminary test of reflected signal reception was carried out.In the experiment,the reflected signals of different polarizations were received,the correction power was observed by means of the upper computer software,and the correlation results between B1C and B1I reflection signals were compared.All these verify that the equipment can work normally.
