OHB Italia S.p.A. took part at the beginning of November to #ARSI (Advanced Remote Sensing Instruments) Workshop at ESTEC (#ESA) in the Netherlands, with three abstracts presented by #MarcoGrilli and #PierGiorgioArpesi:
1) THE CHALLENGES OF A GAME CHANGER
The Copernicus Imaging Microwave Radiometer (#CIMR) mission will revolutionize the monitoring of polar regions, offering enhanced spatial resolution, accuracy, and continuity in L-band measurements.
The mission features a multi-frequency radiometer and the largest-ever unfurlable #antenna developed in the world. CIMR delivers precise data on sea ice concentration and sea surface temperature, using innovative #ActiveCalibration and RFI #MitigationTechniques.
Overcoming major engineering challenges, CIMR sets a new standard for Earth observation and operational sea-ice monitoring.
2) ACTIVE COLD LOAD TECHNOLOGY FOR THE CALIBRATION OF THE COPERNICUS IMAGING MICROWAVE RADIOMETER
The Copernicus Imaging Microwave Radiometer (CIMR) mission introduces a breakthrough in #radiometriccalibration with its Active Cold Load (#ACL) technology. Unlike traditional passive calibration methods, CIMR uses internal active targets, offering enhanced precision for monitoring sea ice and ocean parameters. The ACL achieves noise temperatures as low as 70K, ensuring stable and accurate measurements across multiple frequency bands.
This innovative approach sets a new benchmark in Earth observation, boosting the reliability and performance of polar monitoring data.
3) DESIGN STRATEGY FOR RADIO FREQUENCY INTERFERENCE PROTECTION, DETECTION AND MITIGATION OF THE COPERNICUS IMAGING MICROWAVE RADIOMETER
The Copernicus Imaging Microwave Radiometer (CIMR) tackles the growing challenge of radio frequency interference (hashtag#RFI) with a robust design strategy, ensuring data integrity and instrument protection.
To prevent damage and contamination of measurements, CIMR employs advanced filtering and limiter technologies within its RF chain. A detailed analysis of potential RFI sources led to optimized input protections, balancing sensitivity and interference rejection.
This approach safeguards CIMR’s performance, enabling precise monitoring of sea ice and ocean parameters even in crowded frequency environments.
