摘要
简要介绍了三点等间隔线列阵目标定位的原理,证明了目标定位存在唯一解的充要条件是:τ12≠τ23,并给出了它的等价条件,为战斗使用线列阵提供科学选择。同时,指出了时延的距离表达式在不同文献中形式不一致的原因;给出了m个水听器时,由时延进行目标定向的公式。
the article briefly lntroOuces tlae principle ol tlae tlaree-pomt isometric linear array＇s target positioning, and proves that the necessary and sufficient condition of the unique solution of the target positioning is τ12 ≠τ23 , and also gives its equivalent condition in order to provide scientific choice for using linear array in operation. At the same time, it gives the reason of the range expression of the time delay having different forms in different references; and it gives the formula of the target orienting using time delay when it has serveral hydrophones.
