一、引言对于干扰源作无源定位,是一个很有实际意义的研究课题。利用一个观测平台,通过每次对干扰机测到的方位角和俯仰角数据,能对干扰机的位置及轨迹进行估值,这就是所谓二维仅定向目标运动分析(TMA)[1]。文[2]用逻辑推理的方法,对无源定位的数学模型作了精细、严密的分析,得出了二维及三维情况下,对作匀速直线运动的干扰机进行定位的矩阵算法,讨论了测向误差的影响及应用中的问题,并指出该模型是不适用于平台作匀速运动的。
I. INTRODUCTION Passive location for interference sources is a very significant research topic. Using an observation platform, the location and trajectory of the jammer can be estimated from the azimuth and pitch data measured for each jammer. This is known as two-dimensional TMA [1]. In [2], the mathematic model of passive locating is analyzed in a fine and rigorous way by using logic reasoning. The matrix algorithm for locating jamming machines with uniform and linear motion in two-dimensional and three-dimensional cases is discussed. The influence of the error on the direction finding and its application are pointed out, and the model is not suitable for the uniform motion of the platform.
