摘要
Multifrequency scanning microwave radiometer (MSMR), flown on-board Oceansat-I (IRS-P4), is a four-frequency and dual-polarization sensor for oceanographic applications. An extensive ground calibration experiment was conducted prior to launch to evaluate calibration coefficients. This paper presents an overview of the on-board system, details of ground calibration methodology, and expected calibration performance derived from ground calibration data.
