【摘要】：紅外系統(tǒng)作為一種無(wú)源定位系統(tǒng),其特點(diǎn)是被動(dòng)探測(cè),不受電磁干擾,具備測(cè)角功能,且測(cè)角精度高,但本身不具備測(cè)距功能。針對(duì)海面目標(biāo),利用載機(jī)可獲得的參數(shù),采用單站幾何定位技術(shù)實(shí)現(xiàn)對(duì)目標(biāo)的快速定位。本文分析紅外探測(cè)器的幾何定位算法,推導(dǎo)了幾何定位誤差公式,總結(jié)了影響定位精度的因素,并比較了載機(jī)在不同高度、不同俯仰角下對(duì)定位精度的影響。仿真結(jié)果表明,單站幾何定位的精度受載機(jī)高度、俯仰角的影響,在俯仰角較小時(shí),基于單站幾何定位的定位精度極高,具有一定的工程意義。
[Abstract]:As a passive positioning system, infrared system is characterized by passive detection, free from electromagnetic interference, angle measurement function and high angle measurement accuracy, but it does not have the function of ranging. In view of the sea surface target, the single station geometric positioning technique is used to realize the fast positioning of the target by using the parameters that can be obtained by the carrier. In this paper, the geometric positioning algorithm of infrared detector is analyzed, the formula of geometric positioning error is deduced, the factors influencing the positioning accuracy are summarized, and the influence of different height and pitch angle on the positioning accuracy is compared. The simulation results show that the accuracy of single station geometric positioning is very high because of the influence of height and pitch angle of single station geometric positioning, and the positioning accuracy is very high when the pitch angle is small, so it has certain engineering significance.
