RadarCal analyzes radar calibration data.

=== '''Overview''' ===

RadarCal analyzes radar calibration data.

=== '''Prerequesites''' ===

The following items are required:

* Radar data (any Radx supported format, e.g., cfradial)

=== '''Parameter file''' ===

RadarCal uses one parameter file that includes the basic parameters related to data location and field names, which is similar to the parameter files for the other Radx applications.

==== '''Ensure file is up to date''' ====

To obtain the default parameter file, use the following command:

<code lang="bash">/path/to/lrose/install/bin/RadarCal -print_params > param_file_name</code>

If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:

<code lang="bash">/path/to/lrose/install/bin/RadarCal -params orig_param_file_name -print_params > new_param_file_name</code>

==== '''Important parameters''' ====

Cal circuit parameters

* circuit_gain_h: gain through H circuit, dBm
* circuit_gain_v: gain through V circuit, dBm
* coupling_factor_h: coupling factor H pipe, dBm
* coupling_factor_v: coupling factor V pipe, dBm

Analysis parameters

* linear_region_min_dbm: dBm value at low end of linear region
* linear_region_max_dbm: dBm value at upper end of linear region
* noise_region_max_db: dBm value at upper end of noise region

Output results

* output_dir: files will be written to this directory
* global_file_name: name for global output file

=== '''Running RadarCal''' ===

To check all command line options for RadarCal, including debugging options and file paths, type the following command into a terminal.

<code lang="bash">/path/to/lrose/install/bin/RadarCal -h</code>

Once your parameter file is complete, use a command similar to the following to run the application:

<code lang="bash">/path/to/lrose/install/bin/RadarCal -params param_file_name</code>

The user can also specify the location of cfradial files in the following manner:

<code lang="bash">/path/to/lrose/install/bin/RadarCal -f /path/to/cfradial/files/ -params param_file_name</code>
