    • A device and a method for locating a source (1) provided with a microwave transmitter, particularly over short distances in a portion of a plane or space, are disclosed. The location method comprises using at least two antenna pairs (2, 3) positioned outside the area in which the source (1) is moving, positioning the source transmitter in such a way that the antenna pairs (2, 3) pick up the signal therefrom, measuring, for each antenna pair (2, 3), the phase shift between the signals received by each of the antennas (5, 6, 8, 9) of said pair (2, 3), determining the equation of the hyperboloid of revolution representing the locus of points where wave transmission identical to that of the source (1) would correspond to the phase shift ( phi 1, phi 2) measured by each antenna pair (2, 3), and determining the intersection of the hyperboloids of revolution in order to locate the source accurately and with a single solution. Said device and said method are useful for location and detection over short distances.
    • 公开了一种用于定位设置有微波发射器的源(1)的装置和方法,特别是在平面或空间的一部分中的短距离处。 定位方法包括使用位于源(1)移动的区域外的至少两个天线对(2,3),以使得天线对(2,3)拾取信号的方式定位源发射机 对于每个天线对(2,3),测量由所述对(2,3)中的每个天线(5,6,8,9)接收的信号之间的相移,确定双曲面的方程 表示与源(1)的波传播相同的波传播的点的轨迹的旋转对应于由每个天线对(2,3)测量的相移(phi 1,phi 2),并且确定双曲面的交点 的革命,以便准确地定位源,并使用单一解决方案。 所述装置和所述方法对于在短距离上的定位和检测是有用的。
