DS_NAME : Contains ASAR instrument characterization data



Format Version 114.0  

Note 1: As opposed to the other 3 pulses, the P3 pulse does not characterise the transmit or the receive path, but rather the electronics part of the whole calibration path.

  • Calibration pulses are included in the instrument timeline as initial calibration sequences as well as
    during imaging and consist of: a transmit calibration pulse P1/P1a (actually split into two due to the fact that four T/R modules share a single power supply unit, see below),
    a receive calibration pulse P2 and
    a central electronics calibration pulse P3

See chapter 3 3.1. for a discussion of the ASAR instrument components and their roles.

Note 2: Format for data found within Fields# 69 and # 70, as well as Fields# 72 - 84 are as is given in document " ENVISAT-1 ASAR Interpretation of Source Packet Data. PO-TN-MMS-SR-0248 " ( document available from ENVISAT).
