The main objective of the RADARSAT-2 Mode Selection for Maritime Surveillance (R2MS2) project was to identify and recommend ScanSAR-based maritime surveillance modes for RADARSAT-2 (R-2), while also preparing for exploitation of the RADARSAT Constellation Mission (RCM). The primary focus of R2MS2 was on the performance of wide swath, ScanSAR modes of operation including ScanSAR Wide (SCW) and ScanSAR Narrow (SCN). The following maritime surveillance applications were considered: sea ice surveillance; ice island monitoring; iceberg detection; ship detection; wind speed estimation; oil spill detection; and ocean feature detection. Furthermore, several image quality issues were considered: application look-up table (LUT) performance in converting floating point numbers in the processor into integers in the image product; the block adaptive quantization (BAQ) setting for reduction of raw data volume; and noise subtraction for mitigation of the visual impact of the noise floor for low signal to noise ratio acquisitions. Finally, several tools were developed for DRDC Ottawa’s Image Analyst Pro (IA Pro) software test bed to support R2MS2 data processing needs. For the maritime surveillance applications considered, the approach included a combination of theoretical analysis and field trials to gather new data sets of known targets, with validation whenever possible. The trials often focused on the collection of R-2 Fine Quad (FQ) mode imagery such that all linear polarization choic
