【摘要】：通過(guò)建立目標(biāo)相對(duì)運(yùn)動(dòng)坐標(biāo)系和目標(biāo)相對(duì)運(yùn)動(dòng)觀測(cè)模型,研究了在平臺(tái)搖擺影響下,跟蹤系統(tǒng)觀測(cè)到的目標(biāo)運(yùn)動(dòng)狀態(tài)的變化。在分析捷聯(lián)垂直基準(zhǔn)補(bǔ)償原理的基礎(chǔ)上建立了捷聯(lián)垂直基準(zhǔn)平臺(tái)搖擺角補(bǔ)償模型,建立的模型結(jié)合捷聯(lián)垂直基準(zhǔn)系統(tǒng)的測(cè)量能力對(duì)其補(bǔ)償算法進(jìn)行了理論推導(dǎo),使模型適用于實(shí)際捷聯(lián)垂直基準(zhǔn)系統(tǒng)。通過(guò)建立模型以及仿真研究了平臺(tái)搖擺作用下卡爾曼濾波跟蹤精度的變化,指出了擺造成卡爾曼濾波跟蹤精度降低甚至離散的主要原因在于模型誤差增大。設(shè)計(jì)仿真實(shí)驗(yàn)驗(yàn)證了結(jié)論的正確性,為進(jìn)一步改進(jìn)跟蹤手段提供了理論參考。
[Abstract]:By establishing the relative moving coordinate system of the target and the observation model of the relative motion of the target, the changes of the moving state of the target observed by the tracking system under the influence of platform swing are studied.Based on the analysis of the principle of strapdown vertical reference compensation, the swinging angle compensation model of strapdown vertical reference platform is established, and the compensation algorithm is theoretically deduced based on the measurement ability of strapdown vertical reference system.The model is suitable for the practical strapdown vertical reference system.Through modeling and simulation, the change of Kalman filter tracking accuracy under platform swinging is studied. It is pointed out that the main reason that the pendulum causes Kalman filter tracking accuracy decrease or even discrete is the increase of model error.Simulation experiments are designed to verify the correctness of the conclusion, which provides a theoretical reference for further improving the tracking method.
