【摘要】：在艦船海上校飛過程中,測(cè)量解算飛機(jī)相對(duì)艦船的位置會(huì)產(chǎn)生一定的誤差。采用直接算法在解算中沒有對(duì)粗大誤差和GPS信號(hào)缺失進(jìn)行處理,解算結(jié)果誤差較大。提出了一種改進(jìn)的相對(duì)位置解算算法。通過仿真實(shí)驗(yàn),從方位角、俯仰角和距離3個(gè)方面,對(duì)改進(jìn)算法的解算精度和直接算法的解算精度進(jìn)行分析比較,仿真結(jié)果表明,改進(jìn)算法能很好的提高相對(duì)位置解算精度。
[Abstract]:In the course of ship flight at sea, there will be some errors in measuring the position of the aircraft relative to the ship. The gross error and the missing of GPS signal are not processed by the direct algorithm. An improved relative position algorithm is proposed. Through simulation experiments, the accuracy of the improved algorithm and that of the direct algorithm are analyzed and compared from three aspects: azimuth angle, pitch angle and distance. Simulation results show that the improved algorithm can improve the accuracy of relative position calculation.
