单站航路机动对纯距离目标定位精度影响分析
Effect of single observer maneuvering trajectory on localizing precision in range-only target location
摘要
Abstract
For the problem of positioning and tracking precision in range‐only target motion analysis for single observer ,based on target position tracking lower limit CRLB (cramer‐rao lower bound) , the geometric dilution of precision (GDOP) was taken as the optimal performance indicator .When the observer moved in uniform linear motion with one turning action and in uniform circular motion ,the influence of the route of observer on the target location precision were analyzed by least square algo‐rithm .The simulation results indicate that the observer route has great impact on the target location precision with range‐only measurement ,so a suitable observer route can be chose to improve the per‐formance of the position and tracking algorithm and the target location precision .关键词
