紅外及微波定標(biāo)試驗(yàn)用空間環(huán)模設(shè)備研制

Design of space environmental simulation facility for calibration of microwave and infrared instruments

摘要: 為了滿足星載光學(xué)遙感儀器紅外定標(biāo)試驗(yàn)和星載微波遙感儀器微波真空定標(biāo)試驗(yàn)的需求，上海衛(wèi)星工程研究所研制成一套專用空間環(huán)模設(shè)備，該套設(shè)備在紅外定標(biāo)用20 K冷屏制冷方式的基礎(chǔ)上，采用5臺G-M制冷機(jī)組合冷卻冷屏，冷屏溫度可降至20 K以下。同時(shí)，該設(shè)備是國內(nèi)第一臺微波真空定標(biāo)試驗(yàn)設(shè)備。試驗(yàn)證明設(shè)備各系統(tǒng)達(dá)到設(shè)計(jì)指標(biāo)要求。

Abstract: To calibrate the remote sensing infrared instruments and microwave instruments on satellites, a space environmental simulation facility is designed in Shanghai Institute of Satellite Engineering. The facility uses five G-M refrigerators to cool the cryo-panel to below 20 K in experiments. This is the first facility for the calibration of both microwave and infrared remote sensing instruments in China. It is shown by experiments that the performance of the facility can satisfy the requirements in the corresponding design specifications.
