Embodiment Construction

[0068] Such as figure 1 As shown, a radar network vertical cross fusion positioning method is characterized in that: two radars Rd i and Rd j The network is used to perform synchronous overlapping and simultaneous detection of the moving target T in the airspace, and the measured values ​​are [R i θ i beta i ] T and R j θ j beta j ] T , where R is the slant distance, θ is the azimuth angle, β is the elevation angle, and the configuration position of the network fusion center is [L B H] T , where L is the longitude, B is the latitude, H is the altitude, and the configuration positions of the radar centers of the two groups are [L i B i h i ] T , [L j B j h j ] T , and the center coordinates of the two radar fusion centers are respectively Among them, the coordinates of the center of the station are Cartesian coordinates of the northeast sky, and the coordinate components are x, y, z. The coordinates of the center of the fusion center of the target T ar...

Abstract

The invention discloses a radar network vertical line cross fusion positioning method and an error solving method, including the vertical line cross fusion positioning method and the vertical line cross fusion positioning method's error solving method. The invention is used in a radar networking system to solve data fusion and intelligent auxiliary decision-making, improve the target positioning and tracking accuracy of the networking system, improve the error calibration accuracy of the networking system, and evaluate the spatial distribution of the detection accuracy of the networking system.

Description

technical field [0001] The invention relates to the field of radar algorithms, in particular to a radar network vertical line intersection fusion positioning method and an error resolution method. Background technique [0002] The radar network fusion positioning method, which is similar to the radar network vertical cross positioning technology, is mainly available for public inquiry. The article "Radar Network Triangle" published by Zhao Wenbo et al. Positioning Algorithm and Its Error Analysis", the article is based on the typical triangular space structure composed of two networked radars and the detected target, and uses the relationship between the corners of the triangle to locate and calculate the position of the target in the airspace. The disadvantage of this method is that the accuracy of target resolution is closely related to the angle formed by the two networked radars / targets. When the angle is in the range of 40 degrees to 120 degrees, the accuracy of positio...
