An Array Design Method and Error Analysis for Terminal Trajectory Measurement

This paper introduces the implement method of system ,direction finding array design, time delay estimation of terminal trajectory measurement system. To measure the elevation angle in a vertical plane, discusses the azimuth angle, elevation angle measurement method and error analysis of planar cross array, five element conical array, symmetrical three-dimensional four elements array. After simulation the paper pointed out the last two arrays are better for terminal trajectory measurement based short baseline array.
