摘　　要：此文提出了采用双天线接收两个导航台的信号进行干涉测向,利用信号到达目标的时间差实现导航定位的方法,并以我国南海罗兰-C台链几何配置为参照,仿真分析了典型区域的定位精度和误差性能,验证了该方法的可行性。In this paper a novel method of navigation is presented, which adopts double antennas to receive the signal of two navigation stations and realize interferometric DOA and DOT.The algorithm of DOA jointed DOT location are introduced in detail; the simulation of the location accuracy and the location error performance are made for the type working area referred to the geometric location of the South China Loran-C chain, with the result that the method is feasible.
