Embodiment Construction
[0034] Since the essence of the multi-source passive sensor target position estimation method is to locate the target according to the principle of the corners of the triangle, two or more passive sensor target azimuth measurements are required to estimate the target position. When target monitoring is performed on a specific monitoring area, the position and quantity of sensors are determined by the mean variance calculation and analysis method of the present invention, so as to achieve the optimal estimation of the target position in the area.
[0035] First, the monitoring area is divided into grids to form a grid matrix, and the center coordinates of each grid in the grid matrix are determined. According to the needs of engineering practice, the length of the target position estimation accuracy index is used as the grid side length; secondly, the selection The preset position and quantity of sensor measurement stations, as a set of sensor deployment scheme, set the distance...
