Spectrum is PrismSoft Technologies Radar Processing Package. This product inputs raw radar data and processes it to display fully calibrated RCS (Radar Cross Section) plots. Various filters can be applied to the processed data. 2-d and 3-d, rectilinear and polar plot formatting is available. It currently supports processing of data from SPC MKIV, and a proprietary radar system. The modular software design allows other custom formats to be added quickly. The Spectrum user interface is a "tabbed" screen, allowing 1 click access to the input pages. This design allows additional tabs to be added for program expandability or custom additions a customer may need. A primary dialog, accessable from any page, allows the user to selct the data file for processing, save/recall predefined parameter setups and display the file header. The start reduction, and exit program buttons may also be selected from any page.
The Spectrum Process Page is the primary processing/plot setup page. This dialog allows the user to select the processing and display parameters for each plot. Up to 16 unique plots may be processed and displayed simultaneously. The data can be plotted into a separate window, or overplots may be defined to display different data in the same window. A Data Processing tab page on this dialog allows the user to specify additional processing parameters (i. e. Calibration, Background Subtraction, ...). This design allows a simple method to easily add tabs for new processing capabilities. Additionally, the interface allows the option to automatically print the output plots, save the plots to a bitmap image, or save the processed data to a file. The user may input the x,y and/or z axis display data, or define a plot type (i.e. "Phase vs. Azimuth", RCS vs. "Burst vs. Frequency", ...) for easy drop down access to the axis inputs. The Spectrum user interface allows the operator to define the x,y, and/or z axis to be the following data:
- Azimuth
- Elevation
- Roll
- Time
- Burst
- Frequency
- Range
- Doppler
- DownRange
- CrossRange
- RCS
- Phase
- I
- Q
The Spectrum Plots - Configure page defines user plot display options, such as plot colors, and plot menu defaults. The user may define colors for line plots trace, plot background, plot grid, plot tic marks, axis titles, and header labels. Additionally, each overplot trace color may be individually selected. The interface allows the user to select a saved bitmap default resolution. Since printer resolution is much higher than screen resolution, for printed plots, the data is replotted to a high-resolution bitmap before being sent to the printer. This default resolution is selected as a divisor of the current printer maximum resolution.
The plot displays consists of a Multiple Document Interface window, with each plot in a separate frame. Each window may be resized to display the full screen plot resolution. Mouse tracking allows the user to zoom in on individual features, display the xyz data points, or perform data statistics about a marked polygon region. Menu options allow the plots to be saved as bitmap files, or sent to a printer. The data may also be save in an ASCII output file. (An option on the GUI allows these options to occur automatically, if desired).
