对海上特种目标微波被动定位的精度研究

Study on Microwave Passive Location Precision Against the Special Target on the Sea

介绍了干涉仪测向的基本原理,进行了精度分析。针对测向精度问题,提出一种针对海上大型特种目标的微波被动干涉仪定位的联合算法公式,并且证明了该公式的最优性,验证了利用此公式可以极大地提高对海上大型特种目标的测向精度。

The paper introduces the direction- finding fundamental of the interferometer, analyses the precision. A new combined algorithm of the microwave interferometer aiming at the large special target on the sea is given. The algorithm expression , proved the better than others, can improve the direction - finding precision gready.
