Signal Chain

Introduction

Signal Chain (SCh) is a radar data processing library developed using Python at JRO. SCh provides modules to read, write, process and plot data.

Installation

Install system dependencies, clone the latest version from here and install it as a normal python package, we strongly recommend to use Anaconda or a virtual environment for the installation.

Dependencies

  • GCC (gcc or gfortran)
  • Python.h (python-dev or python-devel)
  • Python-TK (python-tk)
  • HDF5 libraries (libhdf5-dev)

Linux based system (e.g. ubuntu)

$ git clone http://jro-dev.igp.gob.pe/rhodecode/schain/
$ cd schain
$ git checkout `schain-branch` (optional)
$ sudo pip install ./

MAC Os

$ brew install python
$ git clone http://jro-dev.igp.gob.pe/rhodecode/schain/
$ cd schain
$ git checkout `schain-branch` (optional)
$ sudo pip install ./

Docker

Download Dockerfile from the repository, and create a docker image

$ docker build -t schain .

You can run a container using an xml file or a schain script also you need to mount a volume for the data input and for the output files/plots

$ docker run -it --rm --volume /path/to/host/data:/data schain xml /data/test.xml
$ docker run -it --rm --volume /path/to/host/data:/data --entrypoint /urs/local/bin/python schain /data/test.py

CLI (command line interface)

Signal Chain provides the following commands:

  • schainGUI: Open the GUI
  • schain: Signal chain command line

First Script

Here you can find an script to read Spectra data (.pdata), remove dc and plot spectra & RTI

First import SCh and creating a project

#!/usr/bin/python

from schainpy.controller import Project

prj = Project()
prj.setup(
    id = '100',
    name='test',
    description='Basic experiment'
    )

Add read unit and operations

read_unit = prj.addReadUnit(
    datatype='Spectra',
    path='/path/to/pdata/',
    startDate='2014/01/31',
    endDate='2014/03/31',
    startTime='00:00:00',
    endTime='23:59:59',
    online=0,
    walk=0
    )

proc_unit = prj.addProcUnit(datatype='Spectra', inputId=read_unit.getId())

op = proc_unit.addOperation(name='selectChannels')
op.addParameter(name='channelList', value='0,1')

op = proc_unit.addOperation(name='selectHeights')
op.addParameter(name='minHei', value='80')
op.addParameter(name='maxHei', value='200')

op = proc_unit.addOperation(name='removeDC')

Plot data & start project

op = proc_unit.addOperation(name='SpectraPlot')
op.addParameter(name='id', value='1')
op.addParameter(name='wintitle', value='Spectra')

op = procUnitConfObj1.addOperation(name='RTIPlot')
op.addParameter(name='id', value='2')
op.addParameter(name='wintitle', value='RTI')

prj.start()

Full script

#!/usr/bin/python

from schainpy.prj import Project

prj = Project()
prj.setup(id = '100',
                 name='test',
                 description='Basic experiment')
read_unit = prj.addReadUnit(datatype='Spectra',
                                   path='/path/to/pdata/',
                                   startDate='2014/01/31',
                                   endDate='2014/03/31',
                                   startTime='00:00:00',

                                   online=0,
                                   walk=0)

proc_unit = prj.addProcUnit(datatype='Spectra',
                                   inputId=read_unit.getId())

op = proc_unit.addOperation(name='selectChannels')
op.addParameter(name='channelList', value='0,1')

op = proc_unit.addOperation(name='selectHeights')
op.addParameter(name='minHei', value='80')
op.addParameter(name='maxHei', value='200')

op = proc_unit.addOperation(name='removeDC')

op = proc_unit.addOperation(name='SpectraPlot')
op.addParameter(name='wintitle', value='Spectra', format='str')

op = procUnitConfObj1.addOperation(name='RTIPlot')
op.addParameter(name='wintitle', value='RTI', format='str')
