【摘要】:傳統(tǒng)的檢校安置角誤差的方法依靠人工量測(cè)重疊航帶同名特征間的偏移來(lái)估計(jì)安置角誤差,但是同名特征的真實(shí)位置難以獲取,并且人眼瞄準(zhǔn)誤差的存在降低了檢校精度。因此設(shè)計(jì)了一種定標(biāo)器來(lái)解決同名特征的獲取難題。首先介紹了定標(biāo)器的結(jié)構(gòu)特點(diǎn)和設(shè)計(jì)原理,然后制作了縮放模型并進(jìn)行了半仿真地面掃描實(shí)驗(yàn),分析了定標(biāo)器的可用性。最后制作了實(shí)物進(jìn)行飛行實(shí)驗(yàn)進(jìn)一步證明其設(shè)計(jì)的合理性。研究結(jié)果表明定標(biāo)器的設(shè)計(jì)是合理的。
[Abstract]:The traditional method of calibrating the settlement angle error is based on the migration between the same name features of the overlapped ship belt by manual measurement, but the true location of the same name feature is difficult to obtain. And the existence of human eye aiming error reduces the accuracy of calibration. Therefore, a calibrator is designed to solve the problem of acquiring the same name features. Firstly, the structural characteristics and design principle of the calibrator are introduced. Then the scaling model is made and the semi-simulation ground scanning experiment is carried out to analyze the availability of the calibrator. Finally, a flight experiment is made to further prove the rationality of the design. The research results show that the design of the calibrator is reasonable.
