This is because:
1. The cross-track antenna resolution is proportional to range creating severe layover problems in mountainous terrain.
2. The sidelobes from the 30 microsecond pulse duration mask out some of the returns that otherwise would have had a high enough signal to noise ratio.
3. The range to target is greater so the spherical spreading power loss is greater leading to a lower signal to noise ratio.EnglishUKS/CRESISNASA NSIDC DAACNASA National Snow and Ice Data Center Distributed Active Archive Centerhttps://nsidc.org/daacData Center ContactNSIDCUser Servicesnsidc@nsidc.org1-303-492-6199National Snow and Ice Data CenterCIRES, 449 UCBUniversity of ColoradoBoulderCO80309-0449USAHTTPS8 GBPNGHTTPS854 MBJPEGHTTPS45 MBKMLHTTPS151 GBMATAkins, Torry Lee. 1999.

This data set contains radar echograms taken from the Center for Remote Sensing of Ice Sheets (CReSIS) ultra Multichannel Coherent Radar Depth Sounder (MCoRDS) over land and sea ice in the Arctic and Antarctic. The data were collected as part of Operation IceBridge funded aircraft survey campaigns.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/irmcr1b-v001-userguide.pdfIceBridge MCoRDS L1B Geolocated Radar Echo Strength Profiles, Version 1 User GuideGET DATAhttps://daacdata.apps.nsidc.org/pub/DATASETS/ICEBRIDGE/IRMCR1B_MCORDSxyEcho_v01/HTTPSPROJECT HOME PAGEhttp://nsidc.org/data/icebridge/index.htmlIceBridge Product Web SiteVIEW RELATED INFORMATIONhttps://cms.cresis.ku.edu/research/sensors-development/radarUniversity of Kansas - CReSIS Sensors Development / RADAR Web PagePROJECT HOME PAGEhttp://www.nasa.gov/mission_pages/icebridge/index.htmlNASA IceBridge Mission Web SiteCEOS IDN DIFVERSION 9.92011-01-182026-03-03NSIDCVersion SummaryInitial releaseNSIDCMinor Version1On April 12, 2011, 2009 Antarctica MCoRDS data were replaced by V01.1. The original 2009 Antarctica data were processed through a temporary process with quick look data products only. V01.1 data are produced from full Synthetic Aperture Radar (SAR) processing. 2009-10-162009-11-1802On May 16, 2011, the 2010 Antarctica MCoRDS data were replaced by V01.2. The initial 2010 Antarctica data release was a quick look product released immediately upon return from the field. It was Synthetic Aperture Radar (SAR) processed, but the cross-track array processing was greatly simplified. The V01.2 release is the standard product produced from full SAR processing.2010-10-262010-11-1103On October 17, 2011, the V1.02 2009 and 2010 Antarctica MCoRDS data were replaced by V01.3. In V1.03, the kml_good directories have been removed. The echogram data product offerings have been trimmed to a single echogram per data nodule. V1.02 included CSARP_csarp-combined, CSARP_standard, CSARP_mvdr, and CSARP_qlook. V1.03 includes only CSARP_standard. All "Data_img_01_YYYY..." and "Data_img_02_YYYY..." files have been removed so that the only files left are the "Data_YYYY..." files. In the case where only a single image file was produced in the past, i.e. "Data_img_01_YYYY..." these have been renamed to "Data_YYYY...". 2009-10-162010-11-1104On 16 November 2012, the 2012 Greenland data were replaced with Version 01.4. One data segment was added and one segment was removed from the original 2012 Greenland data posted in July 2012. All of the 2012 Greenland data have been reprocessed but the difference in content between Version 01.3 and 01.4 should be negligible.2012-03-272012-05-170NSIDCUpdate Frequencyupdated 2013NSIDCSpatial Reference SystemsEPSG:3031WGS 84 / Antarctic Polar StereographicEPSG:3413WGS 84 / NSIDC Sea Ice Polar Stereographic NorthNSIDCLevel of ServiceStandardNSIDCFull Dataset CitationLeuschen, C.
