设双机同向同速沿直线飞行,利用单基中点测向法,通过两次测量目标的时差,即可在两个不同位置处得到目标的方位角,在此基础上,基于三角定位原理即可获得目标距离的线性解析解。与平面三机时差或双机测向交叉定位法相比,借助单基中点测向法所得到双机时差定位法具有更好的定位精度。 Let the two machines fly in a straight line at the same speed and at the same speed. By using the single center mid-point direction finding method, the azimuth of the target can be obtained at two different positions by measuring the time difference of the target twice. On this basis, The principle can get a linear analytic solution of the target distance. Compared with the plane three-machine time difference or double-machine cross-directional cross-location method, the dual-machine time-difference positioning method obtained by the single-base mid-point direction finding method has better positioning accuracy.
