【摘要】：為保證HY-2衛(wèi)星高度計(jì)輸出數(shù)據(jù)的準(zhǔn)確性和穩(wěn)定性,提高其對海面風(fēng)速的測量精度,提出了一種基于脈沖重建型有源定標(biāo)器對HY-2高度計(jì)后向散射系數(shù)進(jìn)行在軌定標(biāo)的方法,開展了在軌定標(biāo)實(shí)驗(yàn),得到了定標(biāo)因子。將定標(biāo)因子用于校正高度計(jì)測量的海面后向散射系數(shù),并且與Jason2所測得的后向散射系數(shù)進(jìn)行對比,取得了一致的結(jié)果,驗(yàn)證了方法的可行性和準(zhǔn)確性。
[Abstract]:In order to ensure the accuracy and stability of the HY-2 satellite altimeter output data and improve the accuracy of the sea surface wind speed measurement, An on-orbit calibration method for backscattering coefficient of HY-2 altimeter based on pulse reconstruction active scaler is proposed. The calibration experiment is carried out and the calibration factor is obtained. The calibration factor is used to calibrate the sea surface backscattering coefficient measured by the altimeter, and compared with the backscattering coefficient measured by Jason2, the results are consistent, and the feasibility and accuracy of the method are verified.
