All Matlab Toolboxes

NOTE: This list is not complete and is under construction.

List of Signal Processing Toolbox functions:

  • resample: Required for qlook, sar, and analysis processing. Used in data_pulse_compress.m, data_resample.m. Needs to be replaced by open source version of resample.m. See resample below.
  • butter: Required for some operations. Used in hard-coded smoothing operations. Could be replaced by fir_dec and/or filter and re-implemented windowing functions to create filter coefficients.
  • sgolayfilt: Required for sar processing. Used in SAR processor flight trajectory smoothing operations. Also used in some other hard-coded smoothing operations. Same comments as "butter". SAR code needs to be rewritten to avoid usage.

Implemented in the CReSIS toolbox to reduce the dependence on the Signal Processing Toolbox:

  • boxcar
  • tukeywin
  • hanning
  • chebwin
  • medfilt1
