Polarization filtering technique is widely used in many fields, for example interference suppression of sky wave in HF radar. Based on the actual wave data of both signal and clutter, the cause for generation of error, way of error reduction and improvement of SIR by using polarization filtering technique are discussed.

极化滤波技术在高频雷达抗天波干扰等领域有着广泛的应用，结合实际雷达测得的目标回波和干扰回波矢量数据，对极化滤波误差产生的原因、减小误差的方法以及利用极化滤波方法提高信干比的有效性进行了详细分析。

It happen'd, being in Company with some Merchants and Planters of my Acquaintance, and talking of those things very earnestly, three of them came to me the next Morning, and told me they had been musing very much urn what I had discoursed with them of, the last Night, and they came to make a secret Proposal to me; and after enjoining me Secrecy, they told me, that they had a mind to fit out a Ship to go to Guinea, that they had all Plantations as well as I, and were straiten'd for nothing so much as Servants; that as it was a Trade that could not be carried on, because they could not publickly sell the Negroes when they came home, so they desired to make but one Voyage, to bring the Negroes on Shoar privately, and divide them among their own Plantations; and in a Word, the Question was, whether I would go their Super-Cargo in the Ship to manage the Trading Part upon the Coast of Guinea?

有一次，我与一些熟悉的种植园主和商人又很起劲地谈论这些事情。第二天上午，有三个人来找我。他们对我说，他们对我昨天晚上的谈话认真思考了一番，特前来向我提出一个建议。但他们说，这建议必须保密。因此他们要求我严守秘密。然后，他们对我说，他们想装备一条船去几内亚。他们说，他们都像我一样有种植园，但最感缺乏的是劳动力。他们不可能专门从事贩运黑奴的买卖，因为他们回巴西后不可能公开出售黑奴，因此，他们打算只去几内亚一次，回巴西后把黑奴偷偷送上岸，然后大家均分到各自的种植园里去。简而言之，现在的问题是，我愿不愿意管理他们船上的货物，并经办几内亚海岸交易的事务。
